70 Ton Water-cooled Units (Portable)

Cold Shot Chillers 70 Ton model WCWC-840-E water-cooled liquid chiller is designed to bring efficient and superior performance to all types of industrial applications. This machine can be used as a central chiller for indoor or outdoor mounting.  These self-contained water-cooled systems are made to accommodate a process cooling requirement.  Water-cooled chillers allow the refrigeration system to operate at lower head pressure, making them more efficient.  Arrangements available with a remote pump and tank.

Water-cooled chillers recirculate water to cool the refrigerant in the brazed plated fluid condenser.  This chiller includes and efficient water-cooled liquid condenser, high efficiency brazed plate stainless-steel copper brazed.  The refrigerant and cooling water from a cooling water source do not come in direct contact with each other, these flow in different pathways.  These units are usually installed indoors.  System capacity is the approximate 840,000 BTU/hr. based on a leaving fluid temperature of 50°F with a condenser water temperature of 85°F.  The 70 Ton portable water-cooled chiller weighs approximately 1,300 lbs. and has dimensions of 98” L x 55” W x 88” H.

Standard Features

70 Ton Water-cooled Chillers (Reverse Flow)

The Cold Shot Chillers 70 Ton reverse flow water-cooled water chiller is well designed footprint with a PLC controlled and self-diagnostics, WIFI/LAN/LTE connectivity for predictive maintenance.  A 70 Ton model WCWC-840-E-RF water-cooled fluid chiller provides 840,000 BTU/Hr. of cooling capacity with 50°F leaving fluid temperature with 85°F incoming condensing water temperature.

Water-cooled chillers are designed to dissipate process heat into a cooling tower or large water body.  These units are used in many applications and can provide a constant performance. Liquid cooled chillers range in size and are typically compact and designed to reside indoors protected from outdoor ambient conditions.  While water cooled chillers can operate more efficient, it still requires an additional cooling tower system that will require additional installation and maintenance.
