An AI sales agent's Enerflex refrigeration package quote, checked before it goes out

An AI sales agent prepares a quote for an Enerflex Fastrak refrigeration package for a gas processing or refining customer: a refrigerant, a compressor type, a driver, a unit design, the duty in tons of refrigeration, the evaporating temperature and the shaft power, with commissioning, onsite construction and aftermarket service. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the refrigerants, compressors, drivers and unit designs Enerflex publishes and returns a verdict, every reason, a line-item quote and the figures it computed.

Scope: Enerflex Fastrak refrigeration packages: eight refrigerants, five oil-flooded screw and centrifugal compressor types, four driver types, skid-mounted, modular and stick-built units, 10 to 20,000 TR, with commissioning, onsite construction and aftermarket service. See everything this validator covers

This validator models Fastrak refrigeration package quotes as described on public Enerflex pages, not just the scenarios shown below.

  • Refrigerants — propane, propylene, ethane, ethylene, mixed refrigerant, ammonia, CO2 and Freons.
  • Compressors and drivers — oil-flooded screw (single stage, compound two-stage, two-stage piggyback) and centrifugal (between-bearing, integrally geared); electric motor, steam turbine, gas engine and gas turbine drivers.
  • Unit designs — skid-mounted units for smaller systems, fully modular units for larger systems and stick-built plants for extremely large systems.
  • What the validator checks — that the refrigerant can reach the temperature, that the compressor type fits the duty and temperature, that the shaft power can deliver the duty and the driver exists at that power with the steam or fuel gas it needs, that a zero-emissions requirement is met, that the unit design fits the duty, that the service term, discount and stated total are allowed.
  • Approvals — a discount above 3 percent (up to 8 percent), a quote total above $20 million and more than 4 units go to a person; a discount above 8 percent is blocked.

Any Fastrak refrigeration package quote that touches these refrigerants, compressors, drivers and unit designs is in scope — not only the scenarios pictured here. Not covered: Enerflex compression packages, processing plants, contract compression and energy-transition products. Enerflex does not publish prices or selection rules, so every price and limit on this page is illustrative.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
A compressor that must fit the duty and the temperatureOnly with care
Each compressor type has a range of duty and a lowest evaporating temperature, and the refrigerant has its own lowest temperature. Product rules can express each, but every pair is a rule someone writes and keeps in step.		Duty, temperature, compressor and refrigerant are checked together on every call.
Shaft power that has to match the dutyOnly with workarounds
The power needed per ton of refrigeration climbs steeply as the temperature falls. A quote form accepts any horsepower, so an undersized driver goes through.		The minimum power is computed from the duty and the temperature and compared with the quoted power.
A driver that needs something from the siteOnly with workarounds
A steam turbine needs a steam supply, a gas engine or turbine needs fuel gas, and a zero-emissions requirement allows only an electric motor. These are facts about the site, not products on the quote.		The site facts are inputs, checked against the driver and its power range in one pass.
Unit design against sizeOnly with care
Skid-mounted, modular and stick-built units each cover a band of duty, and onsite construction does not apply to a skid.		The duty is checked against the band of the chosen design and the options against the design.
A discount whose authority depends on the quoteOnly with care
Up to 3 percent is fine, more needs a sales director, more than 8 percent is never allowed. Approval tiers are standard.		The discount is compared with the computed list charges and checked with every other rule.
A stated total that has to agree with the quoteOnly with workarounds
Units, services, options and a discount make a total that can drift from what is typed on the quote without anyone noticing.		The total is computed from the choices and compared with the total the quote states.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote is saved or a step is completed, so a person often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases
Click to expand
    
Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

    
1The quote has 0 units; at least one is needed.
2The duty of 5 tons of refrigeration per unit is outside the 10 to 20,000 TR range of the Fastrak refrigeration packages.
3The duty of 5 TR is outside the 10 to 1,500 TR range of this compressor type.
4An evaporating temperature of -35 degrees C is below the -30 degrees C this compressor type can reach.
5The shaft power of 40,000 HP per unit cannot deliver 25,000 TR at -95 degrees C.
6The quote total is $81,540,000, above $20 million, so a person should confirm.
7An evaporating temperature of -110 degrees C is outside the range the packages cover, plus 10 down to minus 100 degrees C.
8An evaporating temperature of -110 degrees C is below the -100 degrees C this refrigerant can reach.
9The shaft power of 90 HP per unit is outside the 100 to 40,000 HP range of the packages.
10A gas engine driver is quoted for 6,500 HP per unit; gas engines are used up to 6,000 HP.
11A steam turbine driver is quoted for 800 HP per unit; steam turbines start at 1,000 HP.
12A steam turbine driver is quoted, and the site has no steam supply.
13A gas turbine driver is quoted for 2,500 HP per unit; gas turbines start at 3,000 HP.
14A gas engine or gas turbine driver is quoted, and the site has no fuel gas supply.
15The customer requires zero on-site emissions, and only an electric motor driver meets it.
16A skid-mounted unit is quoted for 1,600 TR; skid-mounted units cover duties up to 1,500 TR.
17A modular unit is quoted for 900 TR; modular units cover duties from 1,000 to 8,000 TR.
18A stick-built plant is quoted for 3,000 TR; stick-built plants are for duties of 4,000 TR and above.
19Onsite construction is quoted for a skid-mounted unit, which is built and shipped complete.
20The aftermarket service term is 11 years; the term runs from 0 to 10 years.
21The quote takes a discount of $95,180 against $3,156,000 of list charges, above the 3 percent that needs a sales director.
22The quote takes a discount of $253,480 against $3,156,000 of list charges, above the 8 percent an agent may offer.
23The quote states a total of $3,106,000; the prices give $3,156,000.
24The quote has 5 units, above 4, so a person should confirm delivery slots.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a quote for an Enerflex Fastrak refrigeration package for a gas processing or refining customer: a refrigerant, a compressor type, a driver, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the refrigerants, compressors, drivers and unit designs Enerflex publishes and returns a verdict, every reason, a line-item quote and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 1 skid-mounted ethylene Fastrak refrigeration package with a single-stage oil-flooded screw compressor and a steam turbine driver of 8,000 HP. The duty is 3,000 TR per unit at an evaporating temperature of -95 degrees C. The rest of the request is on screen. The quote states $8,250,000 in total.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with eight findings, all in one answer. The duty of 3,000 TR is outside the 10 to 1,500 TR range of this compressor type. An evaporating temperature of -95 degrees C is below the -30 degrees C this compressor type can reach. The shaft power of 8,000 HP per unit cannot deliver 3,000 TR at -95 degrees C. The other five are on screen.
    6. 
      
  6. The validator returned eight blocking findings in one answer, led by compressor does not fit the duty and compressor cannot reach the temperature, among others. A check that reads one product or one field at a time would pass most of this; it shows only when the package, capabilities, deployment, onboarding and the stated total are checked against each other.
    7. 
      
  7. What this shows: for a compressor that must fit the duty and the temperature, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the compressor to between-bearing centrifugal, the driver to gas turbine, the unit design to modular, the shaft power per unit to 12,000 HP, the discount to $922,500 and the stated total to $17,527,500.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Not blocked, but held for a person.
    12. 
      
  12. The validator also returns the line-item quote. It starts with Fastrak refrigeration package and Commissioning and start-up; the other line is on screen.
    13. 
      
  13. The eight blocking findings are cleared; one approval remains for a person: discount above 3 percent.
    14. 
      
  14. The agent resubmits once more.
    15. 
      
  15. The revised request. It changes the discount to $369,000 and the stated total to $18,081,000.
    16. 
      
  16. It calls the validator once more.
    17. 
      
  17. This time the validator clears it.
    18. 
      
  18. The validator also returns the line-item quote. It starts with Fastrak refrigeration package and Commissioning and start-up; the other line is on screen.
    19. 
      
  19. The earlier finding is cleared, and the validator's total, $18,081,000, matches the quote.
    20. 
      
  20. Eight problems caught in one call, fixed in two passes, and a clean $18,081,000 quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    21.
