Predictika · Waste-heat power generator quotes

An AI sales agent's Power+ Generator quote, checked before it goes out

An AI sales agent prepares a quote for an organic Rankine cycle generator that turns hot water or waste heat into electricity: a model, a package, the heat source and its temperatures and flows, cooling, sound, grid and service options, with a stated output and total. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model built on the public Power+ Generator datasheet and returns a verdict, every reason and the total it computed.

Scope: ElectraTherm Power+ Generator models 4400B, 4400B+, 6500B and 6500B+ with package, heat source, cooling, sound, combined heat and power, grid and service options. See everything this validator covers

This validator models Power+ Generator quotes, not just the scenarios shown below.

  • Heat source and water — hot-water inlet temperature and flow, cold-water inlet temperature and flow, the 80 F minimum differential and the heat input range, each by model, with exhaust or thermal oil needing an additional heat exchanger.
  • Cooling, sound, grid and output — the liquid loop radiator only with the system package and only above ambient plus its approach, the site sound limit, the supply voltage, and the output the site needs against what the units deliver.
  • Commercial limits and totals — discount approval above 10 percent and a hard limit at 20 percent, service plans to 5 years, 30-day quote validity, the stated output and the stated total against the computed values.

Any Power+ Generator quote that touches these rules is in scope — not only the scenarios pictured here. Not covered: other Ormat products, installation, freight and taxes. The technical operating ranges come from the public datasheet; all prices and commercial rules are modeled and illustrative (see the note at the foot of the page).

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
Operating ranges that differ by modelOnly with care
Each model has its own hot-water limit, flow ranges and heat input range, so every range needs a rule keyed to the model.		The model and the site conditions are in one request and are checked together on every call.
Options that depend on other choicesOnly with care
The radiator needs the system package and a cold-water temperature above ambient plus an approach, and exhaust heat needs a heat exchanger, so each dependency needs its own rule.		Every option is a field of one request, so each dependency is checked on every call.
A stated output and total that must match the computed valuesOnly with workarounds
The output is units times the model rating and the total is built from the model, options, service years and the discount, so separate rules recompute both and compare them with the stated figures.		The stated output and total are fields of the request and are compared with the computed values on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote is saved or a step is completed, so a rep 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 hot-water inlet on the quote is 150 F; Power+ Generators accept inlet water from 158 F.
2The hot-water inlet on the quote is 280 F, above the 270 F limit of the selected Power+ Generator model.
3Higher-temperature heat sources such as thermal oil and exhaust gas need an additional heat exchanger, and the quote has none.
4The hot-water flow on the quote is 80 gpm; the selected model accepts 95 to 365 gpm.
5The hot-water flow on the quote is 300 gpm; the selected model accepts 45 to 240 gpm.
6The cold-water inlet on the quote is 160 F; Power+ Generators accept 39 to 149 F.
7The cold-water flow on the quote is 100 gpm; the selected model accepts 140 to 410 gpm.
8Hot and cold inlet temperatures differ by 70 F; the minimum temperature differential is 80 F.
9The available heat input is 1,800 kWth; the units on the quote accept 400 to 1,700 kWth in total.
10The available heat input is 300 kWth; the units on the quote accept 400 to 1,700 kWth in total.
11The liquid loop radiator and cold water pump come only with the system package; a standalone unit needs site cold water.
12A liquid loop radiator cannot cool water below ambient plus its approach; at 20 F ambient the cold-water inlet must be at least 75 F.
13In combined heat and power mode the cold-water side runs warm (about 140 F in the datasheet example); 100 F is too cold to deliver the hot water output.
14The standard unit produces 78 dBA at 1 m; the site limit is 75 dBA. The sound-attenuated option is needed.
15Even the sound-attenuated option is rated below 70 dBA at 1 m; the site limit is 65 dBA.
16The nominal rating covers 300 to 500 V three-phase at 50 or 60 Hz; 208 V is outside it.
17The site needs 150 kWe, but the units on the quote deliver at most 125 kWe.
18The site needs 5 kWe, below the 12 kWe the units on the quote produce at their lowest output.
19The quote states 150 kWe rated output, but the units on it are rated 125 kWe.
20The quote states a total of USD 470000, but its line items add up to USD 474,000.
21The discount is more than 20 percent of the equipment price, which is above what a quote may carry.
22The discount is more than 10 percent of the equipment price and needs sales management approval.
23The service plan runs 7 years; plans are limited to 5 years.
24A quotation is valid for 30 days; the quote asks for 45 days.
25The rated ambient operating range is 0 to 100 F and extreme environments may need additional equipment; 110 F ambient needs an engineering review.
26The 6,500B+ 150 kWe gross rating is stated at 480 V / 60 Hz; at another supply an engineer should confirm the output.
27The site runs 5,000 hours a year, under the roughly 80 percent uptime (about 7,000 hours) the datasheet cites for suitable applications; a person should confirm the economics.
2812 units on one quote need project engineering review.
29The hot-water inlet on the quote is 290 F, above the 270 F limit of the selected Power+ Generator model.
30The hot-water flow on the quote is 50 gpm; the selected model accepts 95 to 365 gpm.
31The standard unit produces 78 dBA at 1 m; the site limit is 70 dBA. The sound-attenuated option is needed.
32A quotation is valid for 30 days; the quote asks for 60 days.

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 organic Rankine cycle generator that turns hot water or waste heat into electricity: a model, a package, the heat source and its temperatures and flows, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model built on the public Power+ Generator datasheet and returns a verdict, every reason and the total it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 1 Power+ Generator 6500B unit as a standalone unit, running on thermal oil or exhaust heat at 250 F and 200 gpm. It is ready to send. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with five findings, all in one answer. Higher-temperature heat sources such as thermal oil and exhaust gas need an additional heat exchanger, and the quote has none. The liquid loop radiator and cold water pump come only with the system package; a standalone unit needs site cold water. The nominal rating covers 300 to 500 V three-phase at 50 or 60 Hz; 208 V is outside it. The other two are on screen.
    6. 
      
  6. The validator returned five blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other and against the stated total.
    7. 
      
  7. What this shows: for a stated output and total that must match the computed values, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the model to 6500B+, the additional heat exchanger to yes, the hot-water inlet to 300 F, the cooling to site cold water, the stated rated output to 150 kWe and the total stated on the quote to $499,000. Five more changes are on screen.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All five earlier findings are cleared.
    13. 
      
  13. Five problems caught in one call, fixed in one pass, and a clean $499,000 quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    14.
