Chillers & Refrigeration Solutions
Engineered equipment and replacement solutions for comfort cooling, process cooling and industrial refrigeration applications.
Air-Cooled Chillers
Packaged air-cooled chillers for HVAC and process applications, selected around capacity, ambient conditions, refrigerant, efficiency, sound and electrical requirements.
Water-Cooled Chillers
Water-cooled chiller solutions integrated with cooling towers and condenser-water systems for commercial and industrial duties.
Process Chillers
Industrial process chillers configured for machinery, production lines, fluids and temperature-control duties where stable chilled-water performance is required.
Evaporative Condensers
Evaporative heat-rejection equipment for industrial refrigeration systems, including ammonia applications, with coil, fan and water-distribution selection support.
Closed-Circuit Coolers
Closed-loop evaporative coolers that isolate the process fluid from ambient air while retaining the efficiency benefits of evaporative heat rejection.
Refrigeration Heat Exchangers
Coil assemblies and heat exchangers for closed cooling towers, evaporative condensers and industrial refrigeration service.

INDUSTRIAL REFRIGERATION
Ammonia Refrigeration Support
EVAPNEX can support equipment and replacement requirements around ammonia refrigeration heat rejection, including evaporative condensers, closed-circuit coils, fans, drives, water distribution and associated components.
- Evaporative condenser coils
- Closed-circuit heat exchanger coils
- Axial fans and fan blades
- Gearboxes, motors and drive components
- Spray nozzles and water distribution
- Replacement and retrofit support
Chiller Systems & Equipment Options
EVAPNEX supports enquiry-based selection of commercial and industrial chilling systems. The final design, capacity, refrigerant, compliance documentation and available options are confirmed against the selected manufacturer’s technical offer.
Air-Cooled Chillers
Air-cooled packages reject heat directly to ambient air and can be assessed where a condenser-water loop or cooling tower is not desirable. Equipment configurations for enquiry include scroll, screw and low-temperature glycol chillers; other compressor technologies are reviewed against the duty and supplier’s current range.
- Design cooling capacity and chilled-fluid supply/return temperatures
- Maximum summer ambient temperature, installation elevation and available ventilation clearances
- Water or glycol type and concentration, flow, pressure-loss limit and process temperature stability
- Electrical supply, sound restrictions, operating hours, redundancy and footprint
Water-Cooled Chillers
Water-cooled packages transfer condenser heat to a water circuit typically connected to a cooling tower. Enquiries can cover scroll, screw and larger-capacity chiller configurations subject to application and supplier confirmation.
- Chilled-water design duty, inlet/outlet temperatures and flow
- Condenser-water entering/leaving temperatures, flow, available pressure and water quality
- Available cooling tower, pumps and condenser-water infrastructure
- Part-load operating pattern, target efficiency, electrical supply and redundancy
Industrial & Low-Temperature Process Chillers
For production and process duties, tell us the cooling load or process heat input, required fluid temperature range, fluid composition, continuous or intermittent load, process contamination risks and expected operating conditions. Low-temperature glycol systems and heat-recovery options can be investigated where suitable.
Shell-and-Tube Condensers & Evaporators
We welcome complete heat exchanger requirements as well as replacement enquiries supported by an existing equipment nameplate, drawing or photographs. Heat exchangers are selected for the confirmed heat-transfer duty, refrigerant, allowable pressure losses, fluid compatibility, pressure design requirements and service access.
Shell-and-Tube Evaporators
Dry-expansion (DX), flooded and other application-specific evaporator configurations may be considered where available from the selected supplier. Share required evaporating temperature, refrigerant, chilled-water or process-fluid conditions, heat load, flow, fouling allowance and required approach temperature.
Shell-and-Tube Condensers
Water-cooled refrigerant condensers can be reviewed for new chillers, packaged refrigeration equipment or replacement service. Provide heat-rejection capacity, refrigerant and design condensing temperature, condenser-water flow and inlet/outlet temperatures, design pressures, materials and available installation envelope.
Materials, Construction & Documentation
Depending on the duty, enquiries may call for copper-alloy, stainless-steel or titanium tubing, marine-water compatibility, removable tube bundles, specified design codes, test records and dimensional drawings. These are specification requests—not claims that every material, code or certificate is available for every model.
What to Send Us for Technical Selection
Use our single Request a Quote form for chillers, condensers, evaporators and replacement parts. Enter whatever details are available and attach your equipment photographs, nameplate, datasheet or drawing. Missing parameters can be clarified during technical review.
- Equipment type: air-cooled chiller, water-cooled chiller, process chiller, shell-and-tube condenser or evaporator
- Capacity (kW or TR), fluid and refrigerant, design temperatures and flow rates, if known
- Site ambient and available cooling water, electrical supply and operating schedule
- Existing manufacturer/model, equipment dimensions and connection details for replacements
Engineering-Led Selection
Selection should reflect the actual duty: entering and leaving temperatures, ambient design conditions, refrigerant or process fluid, heat load, fouling tendency, materials, electrical supply, sound and maintainability.
