Liquid chiller and water heat pumps – Refrigerator 289-752 kW Thermal 263-686 kW
Nominal cooling capacity 289 - 752 kW. Nominal heat output 263 - 686 kW.
It is a series of liquid chillers and water heat pumps with reverse cycle on the water side designed for outdoor installation with R410A refrigerant gas. These water-cooled liquid chillers respond optimally to the complex requirements of use in the field of industrial process cooling. The multiscroll logic, adopted on the entire series, allows to maximize the performance indices at partial loads, which represent the main share over the operating life of a machine dedicated to air conditioning. Particular attention was paid to the overall dimensions of these units which must be transported inside technical rooms that are often difficult to access.
Seasonal energy efficiency compliant with the requirements of Directive 2009/125 / EC ErP;
High levels of energy efficiency, especially at partial loads;
The extremely compact dimensions allow it to pass even through the most common technical compartments;
Unloading function for unit operation even in extreme conditions;
Sturdy structure, with components of leading international brands, the result of MTA's industrial culture;
Flexibility of use, suitable for use with both tower or well water;
Further energy efficiency thanks to the options with total and partial heat recovery;
Ease of installation and complete accessibility to all components;
Operation with water temperature at the evaporator outlet between 0 ° C and 25 ° C;
Wide range of ambient temperature (from -10 ° C to +45 ° C);
Easy management thanks to a simple microprocessor parametric control with graphic display.
