Water-to-water chillers. TWS series from Thermex.

Main characteristics:

• 34 sizes with cooling capacity from 39 to 450 kW;
• Scroll compressors;
• Operating range of coolant temperatures at the chiller outlet from -14 to +20°C;
• Casing treatment with zinc-containing primer, powder coating RAL 7035;
• Integration into a common control system with Smart Thermex Energy (STE) condenserless chillers;

High efficiency:

• Plate copper-soldered stainless steel evaporators with low hydraulic resistance;
• Electronic expansion valve (EEV);

High reliability:

• Compressor with external thermal protection and crankcase heating;
• Built-in voltage parameter monitoring relay protects the chiller from incorrect phasing and other possible supply voltage failures;
• Built-in high and low pressure relays;
• Built-in high and low pressure gauges;
• Dismountable filter on the freon circuit for ease of maintenance;
• Thick-walled copper pipe;
• Pressure sensor discharge;

Convenient and quick installation:

• Unloading/loading by forklift or crane;
• Compact housing 800 mm wide;
• Simple first start-up;

Wide control system capabilities:

• Controller with 7-inch touch panel;
• Chiller mnemonic diagram on the main screen;
• Simple and user-friendly interface in Russian;
• Accident log with time;
• Basic equipment for connecting to a cloud service for remote control and maintenance (Ethernet connection required);
• Convenient service menu for testing all actuators in manual mode;
• Support for the ModBus protocol (over TCP IP) in the basic configuration;
• Control of cooling capacity by:
• coolant temperature;
• evaporating pressure (compressors are switched off when it drops);
• superheating (compressors are switched off when there is a large superheat);
• discharge pressure (compressors are switched off when the pressure increases);
• Control of external THM hydraulic modules;
• Control of remote TED drycooler;
