Dry coolers are used in many applications in HVAC, in industrial processes, in cogeneration and in refrigeration, when you need to cool a liquid bringing it from a temperature T1 to T2, where T2 is always higher than the ambient temperature. The new series of dry coolers, liquid coolers and oil coolers of HTE are fully customizable according to the needs of the plant. The plant engineer can then count on 6 lines of product [Table], [V-Form], [Drain], [H-Flow], [Jumbo], [X-cross] divided between one and two rows of axial fans, with AC motors or the more efficient EC fans with brushless technology.
The range is so extensive, that it meets the most demanding requirements of thermal capacity, acoustic performance and dimensions, making HTE dry coolers unique for performance, reliability and durability. The dry cooler is designed depending on the customer's requests, to operate different types of fluids: water, solutions of liquid brine with ethylene glycol, propylene gycol, HYCOOL, Freezium but also other types of fluids such as vegetable or synthetic oils, food-liquids or process industry, just to name a few. The dry coolers in "wet"-execution are equipped with an adiabatic device that includes a high-pressure pump and multiple sets of spray atomizers to take advantage of the additional temperature decrease due to the evaporation of water during periods of high outdoor temperature.
The unit can also be equipped with a programmable PLC (optional). Its functions are directly configurable from a Touch screen panel, 7 "(10") size or remotely via MODBUS, PROFIBUS, PROFINET, BACNET. The user then has the ability to display the operating conditions, change the "set point" temperature, find information about scheduled maintenance, check the diagnostics, track listings of alarms; fully compatible for integration into SCADA architectures. Or request multi circuit, surface increased with special hydrophilic fins, pre-painted, copper or subjected to anti-corrosion treatments executions. Special versions with structure and panels made â€‹â€‹entirely of stainless steel are also available.
