General Features
The Thermotar Air-Cooled Chiller is designed for chilled water systems in commercial and industrial applications that require reliable operation, high capacity, and precise temperature control.
The unit integrates the refrigeration circuit, evaporator, and air-cooled condensing system into a single package. As a result, a cooling tower is not required, which simplifies installation and reduces the number of external system components.
Available from 7.5 to 80 tons, the chillers can incorporate one or multiple independent refrigeration circuits depending on the required capacity. In addition, each unit can be supplied with or without an integrated water pump to accommodate the hydraulic requirements of each project.
Air-Cooled Chiller Cabinet
The cabinet is manufactured from pre-painted galvanized steel to provide mechanical strength, durability, and corrosion protection.
Its construction also provides convenient access to the main internal components. Therefore, inspection and service procedures can be performed efficiently.
Furthermore, cabinet configurations can be adapted to different environmental conditions and installation requirements.
Air-Cooled Condensing System
The condensing system incorporates Thermocoil® air-cooled condenser coils and axial fans to reject heat from the refrigeration circuit.
Fan quantity and configuration are selected according to unit capacity, ambient temperature, and project design conditions. Consequently, the condensing section can be optimized for the specific operating environment of each installation.
Scroll Compressors
Thermotar air-cooled chillers are available with Scroll compressors selected according to cooling capacity, refrigerant, and operating conditions.
Depending on the required capacity, the unit can incorporate one or multiple compressors. Multiple independent refrigeration circuits can also be provided, allowing improved capacity control and greater operational flexibility.
Evaporator
The evaporator transfers heat from the chilled water circuit to the refrigeration system, allowing the unit to supply water at the required temperature.
During selection, several operating parameters are considered, including thermal capacity, water flow rate, and entering and leaving water temperatures. In this way, the evaporator can be matched to the specific requirements of each chilled water system.
Condenser Coil
Thermocoil® condenser coils are manufactured with copper tubes and aluminum fins for efficient heat transfer and reliable performance.
For installations exposed to aggressive environments, optional copper/copper coils are available. Additionally, Luvata anti-corrosion coatings can be specified for coastal areas and other highly corrosive conditions.
Water Circuit
The Air-Cooled Chiller can be supplied with or without an integrated circulation pump, depending on the hydraulic configuration of the project.
Water flow rate, entering and leaving water temperatures, available pressure, and system operating conditions are considered during equipment selection. Therefore, the hydronic configuration can be adapted to the specific requirements of each installation.
Available Refrigerants
Configurations are available for R-410A, R-32, R-454B, and R-290.
Refrigerant selection depends on unit capacity, operating conditions, safety requirements, and applicable regulations. This flexibility allows the equipment to be configured according to the technical requirements of each project.
