Water cooled chillers HT-Cooling CS-BZ series

Description

HT-Cooling CS-BZ process water chillers are designed as a safe, reliable, and energy-efficient solution for process water cooling in a wide range of industrial applications. The series covers a cooling capacity range from 25 to 110 kW and includes eight models in four different frame sizes, allowing precise selection according to application needs.

The robust frame is made of galvanized steel with a polyester powder coating (RAL 9002), providing high resistance to weather conditions and suitability for outdoor installation. On/off scroll compressors in tandem configuration ensure high efficiency and reliable performance, while the compressor compartment is designed for safe access and easy maintenance.

The R513A refrigerant, classified as A1 (non-toxic and non-flammable), guarantees maximum operational safety, making the units suitable even for installation inside production facilities. Heat rejection is provided by axial fans with controlled condensation, optimizing thermal efficiency and reducing energy consumption. An EC fan version is available as an option.

The hydraulic circuit can be configured in several versions – with an integrated pump and tank, with a pump only, or without both pump and tank. Up to five different pump types are available, including run / stand-by configurations. All hydraulic components are compatible with glycol mixtures up to 35% with corrosion inhibitors. The standard hydraulic equipment includes shut-off and check valves, tank level control, air vent, vacuum breaker, and safety valve.

A high-efficiency brazed plate evaporator ensures excellent performance even at low water flow rates. Thermal insulation made of closed-cell material minimizes heat losses. Unit operation is managed by an advanced electronic controller, available either in a standard version or with an optional 7" touch screen. The control system allows dynamic adjustment of outlet water temperature based on ambient conditions, management of multiple units in a network, pump activation during anti-freeze alarms, and supports RS485 communication with Modbus or Carel protocols.

Standard equipment includes automatic water filling, water circuit by-pass, Y-filters on water inlet and filling line, air filters, temperature and pressure sensors, alarm relays, expansion valve, electrical protections, and remote ON/OFF control. Optional accessories and upgrades are available to meet specific operating requirements.
