As a leading global brand in industrial enclosure climate control solutions, German Rittal has decades of technical accumulation in the field of electrical cabinet heat dissipation and constant temperature control. Model 1050500 belongs to the classic Compact economical series of cabinet air conditioners, which is specially developed for small and medium-sized industrial electrical control cabinets, widely used in CNC machine tools, automation production lines, new energy equipment, packaging machinery, metallurgical equipment and other industrial scenarios.
This wall-mounted cabinet air conditioner adopts an integrated compact structural design, with RAL7035 standard industrial gray cold-rolled steel shell, stable and anti-corrosion. It uses environmentally friendly R134A refrigerant to realize efficient closed-loop heat exchange, effectively discharging the heat generated by internal PLC, frequency converters, relays and other electrical components out of the cabinet, avoiding high-temperature aging, short circuit and failure of precision electronic parts. The internal protection level reaches IP54, which can effectively block dust, water splash and moist air, adapt to harsh factory workshop environments, and provide reliable constant temperature protection for electrical control systems all year round.
The operating temperature range of this unit is set between 20ºC and 50ºC, which perfectly matches the optimal working temperature of most industrial electrical components. It is equipped with an independent high-temperature alarm function. Once the internal temperature of the cabinet exceeds the safe threshold, the device will send out a switch signal to remind on-site maintenance personnel to troubleshoot in time, greatly reducing the risk of equipment shutdown caused by overheating. With a net weight of 17kg and overall dimensions of 280mm×550mm×180mm, the compact size will not occupy extra installation space, supporting wall-mounted and semi-recessed embedded two installation methods, flexible to adapt to different cabinet layout requirements.

1. Product Overview
As a leading global brand in industrial enclosure climate control solutions, German Rittal has decades of technical accumulation in the field of electrical cabinet heat dissipation and constant temperature control. The SK3370320 belongs to the classic Compact economical series of cabinet air conditioners, which is specially developed for small and medium-sized industrial electrical control cabinets, widely used in CNC machine tools, automation production lines, new energy equipment, packaging machinery, logistics intelligent equipment and other industrial scenarios.
In the actual industrial production process, a large number of electrical components such as PLC, frequency converter, servo driver will continuously generate heat during long-term operation. High temperature will accelerate the aging of circuit boards, shorten the service life of precision electronic components, and even cause sudden equipment shutdown, bringing huge economic losses to enterprises. Rittal SK3370320 cabinet air conditioner uses compression refrigeration cycle principle to continuously transfer the heat inside the closed electrical cabinet to the external workshop environment, forming an independent internal air circulation, which can not only accurately control the internal constant temperature of the cabinet, but also isolate external dust, oil mist and humid air, realizing dual protection of temperature control and environmental isolation for electrical equipment.
This model adopts an integrated compact structural design, the overall size is only 280mm×550mm×180mm, which greatly saves the installation space of the cabinet. The standard RAL7035 gray electrostatic spray shell is consistent with the color of most Rittal standard cabinets on the market, which can keep the overall appearance of the equipment neat and standardized. The built-in intelligent digital temperature control system can set the target temperature within the range of 20ºC to 50ºC, with a temperature control accuracy of ±1ºC. Once the internal temperature exceeds the set safe threshold, the equipment will automatically trigger the high-temperature alarm signal, and feed back the fault information to the user's remote control terminal through the signal relay, which is convenient for maintenance personnel to troubleshoot in the first time.
All SK series cooling units have passed DIN3168, EN815 international industrial performance testing standards, each product will undergo continuous high-temperature aging test, pressure sealing test and dust-proof reliability test before leaving the factory to ensure stable and continuous operation under harsh working conditions such as high temperature, high dust and high humidity in the workshop. The product uses environmentally friendly R134a refrigerant, zero ozone damage potential, which meets the environmental protection access standards of all countries in Europe, America, Southeast Asia and other regions, and can smoothly pass the local customs safety inspection. We maintain long-term sufficient spot supply of SK3370320 all year round, supporting single sample procurement and bulk project order supply, and can provide complete export certification documents and one-stop logistics customs clearance services for global industrial customers.

3. Five Core Competitive Advantages
3.1 Efficient Stable Compression Refrigeration System
The hermetic high-efficiency compressor matches the precision capillary heat exchange circuit, the refrigeration response speed is fast, the temperature fluctuation is small, it can quickly balance the heat generated by the operation of internal electrical components, effectively avoid equipment downtime caused by high temperature trip, and reduce the failure rate of automated production lines.
3.2 IP54 Dustproof and Moistureproof Safe Protection
The internal air circulation of the cabinet is completely isolated from the external workshop air, which can prevent cutting fluid splash, dust accumulation, corrosive gas and humid air from entering the cabinet, avoid short circuit, circuit board corrosion and component oxidation failure, greatly extend the service life of expensive industrial control spare parts.
3.3 Flexible Dual Installation Design
Two mainstream installation modes are optional, external wall-mounted installation is convenient for on-site rapid transformation of old cabinets without modifying the cabinet structure; semi-embedded installation can save external space, make the equipment layout more neat, and is widely used in standardized intelligent workshop production lines.
3.4 Intelligent Digital Temperature Monitoring & Remote Alarm
The integrated digital controller integrates temperature display, parameter setting and fault alarm functions, with a built-in relay signal output interface. Users can connect the alarm signal to the PLC or remote monitoring system to realize unattended real-time monitoring of cabinet operating status.
3.5 Low Maintenance Cost & Long Service Life
The detachable metal dust filter screen can be repeatedly cleaned and reused, avoiding frequent replacement of disposable filter cotton; the internal fan and compressor adopt maintenance-free design, which greatly reduces the daily operation and maintenance cost of enterprise equipment, and creates long-term stable value for users.
