A cold accumulator is a device similar to a heat accumulator in terms of design and can therefore also accumulate and store heated or chilled water or a water solution and non-freezing liquids. The S-TANK accumulator is capable of handling all certified propylene glycol and ethylene glycol based fluids as well as alcohol solutions. The operating range of CT series is between -40 and +95 degrees. But for operation at such critical temperatures as -40, the tank comes with reinforced insulation. The CT series is often used to ensure correct operation of chillers and high-power solid fuel boilers. Large flange connections are convenient for industrial installations. And the drain hole at the bottom of the tank allows emptying it if necessary. The top part of the tank has a ½” hole with internal thread for installation of control devices or thermometers, manometers, various sensors.

A cold accumulator is used in refrigeration system design for two purposes:

• to arrange an expansion vessel in order to increase the liquid volume in the system and make it more inert.
• to create a cold accumulator that acts as a storage element and creates a certain reserve.

The use of a cold accumulator in air conditioning or refrigeration unit systems offers the following benefits:

• It is possible to reduce the refrigeration unit capacity by 30 up to 40%.
• Reduces capital charges and equipment operating costs
• Responds to the needs of a system with high short-term cooling requirements
• Extends the service life of refrigeration and freezing units by reducing the number of compressor starts. It’s a well-known fact that every extra compressor start-up reduces its durability.
• Reduced power consumption in ON/OFF systems of refrigeration machines and units.
