 Expert Selection and Buying Guide for 500 TR Water Cooled Chiller by DamaTajhiz

If you are looking to purchase a high-quality water cooled chiller with excellent technical specifications, timely delivery, competitive pricing, and professional consultation, you are in the right place.

We hope that by reviewing the following information and contacting the HVAC sales experts at DamaTajhiz, you will have a satisfying and reliable purchasing experience.

Water cooled chillers act as the heart of cooling systems, supplying chilled water at 7°C for HVAC and industrial refrigeration systems. Their operation is based on the vapor compression refrigeration cycle.
In HVAC applications, these chillers provide chilled water for fan coils and air handling units. Compared to air-cooled chillers, water cooled chillers offer higher efficiency.

The 500 TR water cooled chiller DamaTajhiz Model 4DTCHS500 is manufactured with 4 screw compressors from top global brands, based on customer requirements.

Main Components of Water Cooled Chiller 4DTCHS500W by DamaTajhiz

1. Main Body:
   • Constructed from galvanized steel with modern engineering design
   • 4 mm thick heavy-duty electrostatic coated frame
2. Compressor:
   • Scroll or screw compressors from Danfoss, Copeland, Bitzer (IP54 protection)
   • Supports refrigerants R22, R134a, R407C
   • Each compressor includes serial identification for authenticity verification
   • Note: Compressor brand may vary based on order conditions
3. Refrigeration Circuit Control Equipment and Instrumentation:
   • The expansion valve (Expansion Valve) from the original Danfoss brand is an adjustable thermal valve that reduces the pressure of the refrigerant liquid before entering the evaporator and prepares it for evaporation at the evaporator temperature.
   • The 500 TR water-cooled chiller DamaTajhiz Model 4DTCHS500 is equipped with pressure gauges (Pressure Gauge) to control discharge and suction pressures, and also equipped with anti-freeze, flow switch, and thermostat to control the evaporator water temperature.
   • The Oil Pressure Control, which is installed separately for each compressor to control oil pressure, will issue a shutdown command if for any reason the difference between oil pressure and compressor crankcase pressure drops below the allowable limit.
   • The solenoid valve, which is switched on and off by the coil installed on its stem, allows the refrigerant liquid to pass when energized and blocks the flow when the current is cut.
   • The sight glass indicates the amount of refrigerant gas and the level of moisture in the liquid line.
   • The Anti-Freeze system is installed in DamaTajhiz chillers to prevent water freezing inside the evaporator.
   • The DamaTajhiz water-cooled chiller is equipped with a high-quality Dryer Filter, which is used to improve compressor performance and to absorb moisture and impurities in the refrigerant line before entering the compressor.
4. Evaporator:
   • The evaporator of DamaTajhiz water-cooled chillers in various capacities is of SHELL & TUBE type (with a durable steel body), where low-pressure refrigerant flows inside copper tubes and chilled water flows inside the shell.
   • The internal tubes of the evaporator are made of copper with appropriate thickness and equipped with 5-fin aluminum stars to increase the heat transfer coefficient. In addition, the tube sheets are made of ST52 steel, and the baffles are made of Teflon with a thickness of 5 to 7 mm, tested under 400 PSI conditions and manufactured according to ASTM359 / ASME SB359 standards.
   • To prevent heat loss, the outer shell of the evaporator and suction lines are fully insulated with high-quality elastomeric insulation with a thickness of 23 mm and coated with aluminum.
5. Condenser:
   • The condenser of the 500 TR water-cooled chiller DamaTajhiz Model 4DTCHS500 is manufactured and integrated using fully automatic machines and modern technology.
   • The condenser is equipped with seamless copper tubes to maximize heat transfer and efficiency.
   • The main body (shell) of the condenser is made of highly durable steel and is fully insulated at the end of production using 19 mm polyethylene insulation.
   • After manufacturing, the condenser undergoes a hydrostatic pressure test at 10 bar and an air leakage test.
6. Electrical Panel and Electrical Components:
   • The control system and electronic components used in the electrical panel are from top brands including Hyundai, Carel, Schneider, and Siemens.
   • Capability to connect to the Building Management System (BMS), allowing automatic adjustments based on environmental condition changes.
   • Phase protection system to disconnect power in case of three-phase voltage imbalance due to motor feedback issues or network imbalance.
   • Equipped with an automatic circuit breaker to cut off compressor current in case of overload beyond the contactor capacity. If any compressor draws excessive current, the system disconnects it to prevent damage and high costs.
   • Equipped with a main power switch with properly crimped input/output terminals, and the panel cabinet is made of steel sheet with electrostatic powder coating.
