An efficient and sustainable temperature control is essential for process safety in industrial and research applications involving heat generation – from packaging lines to welding equipment to injection molding and laser applications. The automation specialist SMC, known for its versatile portfolio, now offers the INR-244-831 series, a particularly space-saving cooling and heating device. The solution enables environmentally friendly operation in a refrigerant-free, quiet, and low-maintenance Peltier design – suitable for machines as well as workbenches.

In high-performance industries such as mechanical engineering, the laser industry, or life sciences, process engineers rely on powerful cooling and heating devices for circulating media that maintain the set temperature, operate energy- and resource-efficiently, and can be adapted to many applications. With the INR-244-831 series, the specialist for pneumatic and electrical automation technology has expanded its portfolio with a cooling and heating device that conserves resources while offering maximum performance with minimal device dimensions, saving space – with compact dimensions of only B130 × T150 × H210 mm. Thanks to features such as its low height and light weight, the powerhouse can be conveniently installed directly on the machine or on workbenches in tight spaces. And since the Peltier design does not require a refrigerant, the INR-244-831 series can be maintained easily and operated environmentally friendly with minimal effort (possible circulating media: tap water or aqueous ethylene glycol solution, max. 20% or less).

High performance with low noise levels

The immediate environment of the installed cooling and heating device is protected even in the broader sense of the word. Thanks to its quiet construction, the INR-244-831 series can be used even at high power output in environments where low noise levels are desired. Users benefit directly from this strength of the new INR-244-831 series, as it allows installation in machines near the work area without causing significant noise pollution for people or the environment. The reason for this is the low noise level of only 58 dB produced during operation, which can be further reduced to 45 dB with an optional quiet fan.

Stable cooling and heating performance

The key performance indicators of the new SMC cooling and heating device speak for themselves: suitable for ambient temperatures from 10 to 35 °C and a temperature setting range from 10 °C to 60 °C, the INR-244-831 series achieves a temperature stability of ±0.01 to 0.03 °C, a cooling capacity of up to 220 W, and a heating capacity of up to 500 W. The front panel is equipped with a user-friendly display and control panel, as well as a fill level indicator for the circulating medium (media-contact materials: stainless steel and plastic, free of aluminum and copper). This simplifies both operation and maintenance, which is further facilitated by a replaceable dust filter.

Versatility for high-performance industries

Especially in high-performance applications, tight temperature windows must be maintained; otherwise, there is a risk of dramatic losses in product quality and quantity. Machine reliability can also significantly decline if process temperatures leave the optimal range. Specifically for industries such as mechanical engineering, the laser industry, or life sciences, SMC now offers its new cooling and heating devices of the INR-244-831 series as a compact, space-saving powerhouse that not only impresses with high performance but also protects the environment with refrigerant-free, low-noise, and low-maintenance Peltier design – making it a sustainable choice for both industrial and research applications.
