Overview

R410A YEAR-ROUND COOLING MODULAR UNIT

Withair's new generation of year-round cooling modular unit is applicable for industrial applications, and requirements on energy saving and environment protection. It can operate for refrigerant at the ambient temperature of -10℃~48℃ all the year round, with environment friendly refrigerant R410A, advanced electronic expansion valve control technology, efficient shell and tube heat exchanger, EC fan with steplless speed regulation, fully meeting the requirements of various industry applications for chilled water throughout the year.
Efficient, Flexible and Quiet

The perfect combination of sound and efficiency for your small tonnage applications. The Withair's air-cooled scroll chiller offers the perfect combination of flexibility, efficiency and low noise. Available in sizes ranging from 20 to 160 tons with a compact footprint, and it is one of the quieter air-cooled chillers available today. There are multiple levels of efficiency to choose from to comply with your local code requirements.
Perfect Combination for Small Tonnage Applications

Modular Air-cooled Water Chiller Offers the perfect combination of flexibility, efficiency and low noise. Available in sizes ranging from 20 to 160 tons with a compact footprint. There are basic modules of any combination available for different models, and at most 16 modules can be connected in parallel.
Partial Heat Recovery and Total Heat Recovery

Using partial heat recovery or total heat recovery, rejected heat can be redirected through a heat exchanger to provide heat for reheat coils. Unlike a heat pump, a heat recovery unit does not have reversible refrigeration circuits. Heat recovery applications primarily control to a supply heating temperature and typically recover/source energy from the HVAC system chilled water loop for heating use. There must be a cooling load to satisfy a heating load and vice versa. The recovered energy is delivered to the water heating loop by diverting the compressor refrigerant discharge into a water-cooled heat exchanger instead of into the air-cooled condenser.
Gain Reliable Year-Round Comfort

A perfect fit to meet your sustainability and efficiency targets. Enabled by our advanced controller, advanced adaptive control optimize performance. Post-installation, controller can connect with BMS energy analysis and 24/7 monitoring services to assure Withair's Air-cooled Scroll Chillers are continuously optimized for efficiency and uptime.
Integrated Free Cooling

The free cooling option delivers optimal performance by minimizing compressor operation when outdoor air temperatures are low enough to assist in cooling the chilled fluid loop. The integrated chiller fluid-based free-cooling system consists in a set of coils, installed in the same frame as the condenser coils of the chiller refrigerant circuit. Free-cooling coils are installed in series ahead of the evaporator. A set of water regulating valves modulate flow, and allow the coils to be by-passed when ambient temperatures are no longer favorable for free-cooling operation. Free-cooling coils will be all aluminum, flat radiator design type, with low air pressure drop to avoid fan performance degradation.
