Chillers for cooling process equipment. TWC series from Thermex.

Main characteristics:

• 7 standard sizes with cooling capacity from 7 to 38 kW;
• Scroll compressors;
• Outdoor air range for chiller operation from –5 to +43°C;
• Operating range of coolant temperature at the chiller outlet from –7 to +17.5°C;
• Body treated with zinc-containing primer, powder coated RAL 7035;
• Up to two compressors per circuit;
• Low noise level due to the use of EC fans with continuously variable speed;
• Reduced freon charging volume due to the use of microchannel heat exchangers;

High efficiency:

• High efficiency microchannel aluminum capacitors;
• Ability to work at high ambient temperatures, up to +43°C;
• High performance of EC fans with lower power consumption;
• Stainless steel brazed copper plate evaporators with low hydraulic resistance;

High reliability:

• Compressor with external thermal protection and crankcase heating;
• The built-in relay for monitoring voltage parameters protects the chiller from incorrect phasing and other possible supply voltage accidents;
• Each fan with individual motor thermal protection and protective grille;
• Built-in flow switch;
• Mechanical expansion valve (TEV);
• Possibility of installing an air filter on condensers (optional);
• Built-in high and low pressure switches;
• Built-in high and low pressure gauges;
• Built-in circulation pump for pumping process water (permissible sizes of solid particles in pumped water up to 1 mm);
• Thick wall copper pipe;

Convenient and quick installation:

• Compact body;
• Built-in circulation pump;
• Easy first start;
• Less weight and dimensions compared to copper-aluminum capacitors;

Wide range of control system capabilities:

• Controller with graphic color display;
• Simple and convenient interface in Russian;
• Alarm log with time stamp;
• Basic equipment for connecting to a cloud service for remote management and service (Ethernet connection required);
• Convenient service menu for testing all actuators manually;
• ModBus protocol support (via RS-485) as standard;
