Profile

The CAREL CPQ Tool is CAREL’s online Configure-Price-Quote (CPQ) platform developed to help consulting engineers, OEM designers, and design & construct (D&C) contractors correctly select and configure CAREL HVAC and refrigeration products.

In an industry where control systems and accessories often determine whether a project commissions smoothly. CPQ provides a rules-based, manufacturer-validated selection environment.

This is not a generic sales configurator. It is engineering-driven selection software built around real HVAC applications.

Why Selection Software Matters in Modern HVAC Projects

Today’s HVAC projects demand:

Accurate humidification sizing
Correct electronic expansion valve (EEV) pairing
Compatible controller and I/O configurations
Communication protocol alignment (BACnet, Modbus, etc.)
Complete accessory inclusion
Commissioning file compatibility

CAREL Product Categories Supported by CPQ

Below are the key CAREL product groups relevant to consulting engineers and D&C contractors.

1) Humidification Systems

CAREL is globally recognised for humidification technology, and CPQ provides structured selection across:

Electrode steam humidifiers
Resistive steam humidifiers
Gas-to-steam humidifiers
Adiabatic humidification systems
Steam distribution manifolds
Control and safety accessories

For Consulting Engineers

When designing humidification for:

Hospitals and healthcare facilities
Clean rooms and pharmaceutical spaces
Laboratories
Data centres
Commercial comfort systems

CPQ allows designers to:

Determine required capacity from psychometrics
Select application type
Define distribution method
Confirm compatible controls
Generate complete component lists

This ensures humidifier schedules are technically complete and aligned with installation requirements.

2) HVAC Controllers

Control systems often become the weak link between design intent and real-world performance.

CPQ supports configuration of CAREL controllers used in:

Air Handling Units (AHUs)
Rooftop units
Ventilation systems
Packaged plant
Terminal applications

The tool guides users through:

Base controller selection
I/O expansion module matching
Sensor compatibility
Communication protocol options
Power supply and accessory inclusion

For D&C Contractors and Controls contractors

This reduces:

Site variations
Missing I/O points
Late discovery of incompatible modules
BMS integration surprises

3) Sensors & Field Devices

CPQ integrates the selection of:

Temperature probes
Humidity sensors
Pressure transducers
CO₂ sensors
Air quality sensors

Rather than leaving sensors as manual add-ons, CPQ embeds them into the selection logic to ensure:

Electrical compatibility
Correct mounting configuration
Alignment with controller inputs

4) Electronic Expansion Valves (EEVs)

Electronic expansion valves are critical in:

Chillers
Heat pumps
CRAC units
Refrigeration systems
Process cooling equipment

Incorrect valve selection can cause:

Poor superheat control
Compressor inefficiency
Capacity instability
Reliability issues

CPQ supports selection based on:

Refrigerant type
Capacity range
Pressure conditions
Valve size
Compatible driver/controller selection

For OEM Designers & Contractors

CPQ ensures:

Valve and driver compatibility
Correct accessory inclusion
Alignment with CAREL control platforms
Reduction of manual cross-checking between datasheets

This is particularly valuable when designing or upgrading packaged equipment.

Engineering Benefits of the CAREL CPQ Tool

Structured Configuration

The selection path follows a logical technical sequence rather than a product catalogue format.

Compatibility Enforcement

The rules engine prevents incompatible combinations between controllers, expansion modules, valves, and accessories.

Complete Bill of Materials

CPQ generates a comprehensive list of required components — reducing field omissions.

Downloadable Documentation

Engineers and contractors can access:

Technical datasheets
Layout documentation
Installation references
Configuration files

Commissioning Support

By aligning hardware and configuration from the outset, CPQ supports smoother site commissioning.

Final Engineering Perspective

For consulting engineers, it supports technically defensible design documentation.
For D&C contractors, it reduces commercial and commissioning risk.
For OEM designers, it streamlines configuration accuracy.

In a market where HVAC performance is increasingly driven by control precision, accessory alignment, and commissioning readiness, structured selection software like CPQ is no longer optional — it is part of modern design workflow discipline.
