COOL AIR Product Lines We Repair
Our engineers are trained on the full COOL AIR product range. Below are the major product families we service.
Cool Air MicroChill Controllers
Microprocessor-controlled refrigeration management units for precision temperature holding. Common faults include display errors, sensor read failures, and compressor cycling malfunction affecting cooling cycle stability.
Cool Air CompactChiller Range
Self-contained chiller units with integrated pump and control panels for pharmaceutical and biotech cleanroom environments. Typical issues involve coolant circulation sensor faults and thermostat calibration drift.
Cool Air TemperaMate Series
Distributed temperature monitoring and control network for multi-zone industrial facilities. Common faults include wireless communication loss, RTD sensor drift, and relay card failures.
Cool Air RefrigerantLogic PCBs
Standalone circuit boards managing compressor run-time, defrost cycles, and alarm logic. Repair often involves replacing capacitors, relay contacts, and reprogramming EEPROM settings.
Cool Air SensorLink Interface Modules
Signal conditioning and isolation modules for thermocouples, RTD probes, and pressure transducers. Failures include input conditioning faults, isolation diode burnout, and output signal clipping.

Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common COOL AIR Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in COOL AIR equipment arriving at our workshop.
- ✓MicroChill display lockup with no temperature readout — Cool Air MicroChill controllers experience EEPROM corruption when exposed to thermal cycling or supply voltage spikes. The microprocessor halts without displaying temperature or accepting input commands.
- ✓CompactChiller coolant circulation pump runs continuously — Cool Air CompactChiller flow sensor failure or blocked sensor port leads the controller to assume no circulation. The compressor remains enabled indefinitely, raising cabinet temperature dangerously.
- ✓TemperaMate wireless nodes drop offline intermittently — Cool Air TemperaMate remote modules suffer RF interference in Indian manufacturing plants near welding equipment and motor drives. Antenna connector oxidation or PCB trace corrosion degrades signal integrity.
- ✓RefrigerantLogic compressor not starting despite setpoint below temperature — Cool Air RefrigerantLogic relay output stages fail when subjected to inductive load switching surges. Relay contacts weld or open, breaking compressor control signals regardless of logic state.
- ✓SensorLink RTD input reads erratic temperature swings — Cool Air SensorLink isolation amplifiers exhibit gain drift or input coupling capacitors develop leakage. 4-20mA output scaling becomes non-linear, causing wild thermostat response in your control loop.
- ✓Cool Air system alarm code E7 with compressor disable — E7 error on Cool Air controllers indicates high-side pressure transducer signal loss or excessive system pressure. This triggers automatic compressor shutdown to prevent refrigerant overpressure damage.

Frequently Asked Questions — COOL AIR Repairs
Do you repair Cool Air equipment anywhere in India?+
Yes. Synchronics repairs the full Cool Air product range including MicroChill controllers, CompactChiller units, TemperaMate networks, RefrigerantLogic boards, and SensorLink modules. We offer PAN India door-to-door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other cities. All repairs are handled at our Vadodara, Gujarat facility.
How do I know if my Cool Air controller is faulty or if the problem is refrigeration-side?+
Synchronics applies proven diagnostic methodology: we measure actual sensor outputs against the displayed setpoint and temperature readings, test relay and compressor control signals with oscilloscope, and verify pressure transducer calibration against a master gauge. This isolates whether your Cool Air electronic fault is control-side or refrigerant-cycle related, saving unnecessary replacement of mechanical components.
What is the typical repair turnaround for Cool Air cooling controllers?+
Standard Cool Air repairs like board-level component replacement, EEPROM reprogramming, and relay contact service take 5-7 working days door-to-door. Urgent cases are prioritized with 48-hour turnaround on Cool Air units received before 10 AM. We provide loaner controllers for critical pharmaceutical and food-chain applications to minimize downtime.
Can Synchronics retrofit my older Cool Air system with modern wireless monitoring?+
Yes. Synchronics supplies Cool Air-compatible TemperaMate wireless sensor nodes and gateway modules to add real-time monitoring to legacy Cool Air installations. We integrate these alongside existing thermostats and relay panels without major rewiring. Your facility gains cloud-connected temperature logging and alarm notification via WhatsApp and email.
Do you have Cool Air spare parts in stock or must I order from the manufacturer?+
Synchronics maintains a rotating stock of high-failure Cool Air components including relay cards, isolation amplifiers, RTD conditioning modules, and EEPROM chips. For specialized parts like CompactChiller pump seals or rare MicroChill firmware versions, we source directly from Cool Air or authorized distributors with typical lead time of 3-5 days. We advise you during diagnosis if long lead items are required.
How do I send my COOL AIR unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a COOL AIR drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on COOL AIR repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your COOL AIR unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
