High cooling capacities are required in a wide range of industries. Be it a plastic extruder, a paper machine or a laser - sensitive products and components need well-tempered conditions in order to function perfectly. This is how developers and manufacturers achieve optimum process quality and maximum machine performance. However, the cooling and temperature control units that provide the right temperatures require space, and they generate waste heat that has to be dissipated from the hall itself. As a manufacturer, partner and solution provider for pneumatic and electrical automation technology, SMC supplies a large portfolio of proven cooling and temperature control units - and is now presenting a practical solution. With the HRS200 series, the automation experts have developed a cooling and temperature control unit that complies with protection class IPX4 and can therefore also be installed outdoors.

With a cooling capacity of 17.5 kW (50 Hz), a heating capacity of 3.3 kW (50 Hz), a temperature setting range of 5 to 35 °C and a temperature stability of ±1 °C, the air-cooled cooling and temperature control unit from the HRS200 series offers the right performance for demanding cooling tasks. "Because the HRS200 series is used outdoors, we have designed it to offer optimum temperature stability even at sub-zero temperatures," says Kim Holy, Product Manager at SMC. Ambient temperatures from -5 °C to +45 °C are no problem for the HRS200. If the temperature approaches freezing point - for example on particularly cold winter nights - the pump automatically generates heat by circulating the circulating medium, thus preventing possible frost damage. The heating function is also energy-efficient: no electrical heating element is required, as the hot gas generated by the compressor heats the circulating medium at the same time. Kim Holy: "This not only saves the operator valuable space in the hall and he doesn't have to worry about the waste heat from the appliance - he also reduces his energy costs."

All electrical components of the HRS200 series are accessible from the front and the appliance has a seal-free submersible pump. This makes maintenance easy. The circulating medium can also be automatically refilled via a filler opening. The cooling and temperature control unit is controlled via an integrated control panel display on the front of the appliance. This informs the operator of potential malfunctions with 39 different alarm codes. The control system uses the codes to ensure rapid assistance from the customer service department and can announce any necessary pump or fan maintenance. The actual and set values and other parameters can also be conveniently set and read on the large digital display.

"With its particularly robust and IPX4-certified design, the new HRS200 series cooling and temperature control unit is an ideal addition to our product range in this area," says Product Manager Kim Holy. The new cooling variant enables the effective temperature control of demanding applications, such as welding equipment, vacuum pumps and UV drying systems in automotive and mechanical engineering. The devices also reliably control the temperature of laser technology used in 3D printers in the tightest of spaces.
