Superior Performance in Industrial Cooling: Discover the WMU Series Wall-Mounted Industrial Air Conditioners Units

In industrial production facilities, continuously operating machinery and sensitive electronic equipment require industrial cooling. Failure to control ambient temperature can result in equipment failure, production downtime, and serious safety risks.
Conventional climate control systems may be inadequate in such environments. In conditions where humidity, dust, and sudden temperature changes are prevalent, specialised systems capable of withstanding harsh conditions and operating continuously are required. At this point, TMS Group’s WMU Series Wall-Mounted Industrial Air Conditioners Units come into play.

What are WMU Series Wall-Mounted Industrial Air Conditioners Units?

WMU Series Wall Mounted Industrial Type Air Conditioners Units are wall-mounted industrial type air conditioning units specially developed by TMS Group for harsh industrial conditions. It is resistant to high temperature, humidity, dust and chemical exposures. Thanks to its compact structure, it saves space and offers fast integration with “plug-and-play” installation.

What Is the Purpose of WMU Series Wall-Mounted Industrial-Type Air Conditioning Units?

WMU Series Wall Mounted Industrial Type Air Conditioners Units go beyond conventional air conditioners and offer versatile solutions to the demanding needs of industrial facilities. It keeps the ambient temperature constant by working continuously 24/7 for electronic equipment, container systems and battery systems. With its structure that can operate between -25°C and +60°C, it is safely preferred in critical facilities.

Not only temperature but also humidity control extends device life and reduces maintenance costs. Thanks to its advanced filtration system, it provides clean air by filtering dust, particles and chemical gases; this is especially important for control rooms and laboratories.

In dusty environments, the positive pressure feature is activated to prevent harmful substances in the outside air from leaking in.

With the free cooling feature, if the outside air is cool, natural cooling is done without the compressor being activated, thus significantly reducing energy consumption.

In the event of a power failure, it continues to operate on 48VDC emergency power, so temperature control in battery rooms, UPS systems and data centres continues uninterrupted.

WMU Series Wall Mounted Industrial Type Air Conditioners Units Models and Cooling Capacities

TMS Group’s WMU Series Wall Mounted Industrial Type Air Conditioners Units are available in 5 different model options for industrial areas of different sizes and variable heat loads. Each model allows the user to use both single and twin units. Twin structure is preferred not only for capacity increase but also for system redundancy and uninterrupted operation in case of failure.

How WMU Series Wall Mounted Industrial Type Air Conditioners Units Work? High Efficiency with Smart Modes

WMU Series Wall Mounted Industrial Type Air Conditioners Units can automatically switch between various operating modes thanks to their advanced electronic control systems. Basic operating modes are as follows:

1. Normal Cooling Mode (with compressor): When the indoor temperature rises, the compressor is activated. The damper system is closed and contact with the outside air is cut off. The air is cooled through the evaporator and is given back to the indoor environment. This closed circuit maintains constant temperature.
2. Free Cooling Mode (Passive Cooling): When the outside air is cooler, the damper opens and the compressor is deactivated. Filtered outdoor air is taken directly into the indoor environment. Damper opening is automatically adjusted according to the temperature difference.
3. Hybrid Mode (Mixed Operation): In cases where outdoor and indoor temperatures are close, both outdoor air and compressor work together. The system activates the compressor as a backup when necessary. Ideal for seasonal transitions.
4. Positive Pressure Mode: Indoor pressure is increased by letting in a maximum of 30% fresh air. Excess air is exhausted by the exhaust fan and the pressure is stabilised. In this way, the leakage of dirty air from the external environment is prevented.
5. Emergency Mode (Operation with 48VDC): In case of power failure, the device automatically switches to this mode. While the compressor is disabled, fans, PLC unit and sensors continue to operate. The system prevents temperature rise by maintaining basic cooling.

Application Areas of WMU Series Wall Mounted Industrial Type Air Conditioners Units

WMU Series Wall Mounted Industrial Type Air Conditioners Units can be safely used in critical areas where environmental conditions such as temperature, humidity, dust and chemical gases need to be controlled.

• Technical Areas: Transformers, distribution panels, PLC rooms, UPS systems
• Energy Systems: Battery containers, renewable energy systems

• Heavy Industry: Cement, mining, metal processing plants, machine parks
• Maritime and Defence: Ship flats, radar cabinets, military container systems

In all these different application areas, the biggest advantage of WMU Series Wall Mounted Industrial Type Air Conditioners Units is the “plug & play” installation that does not require infrastructure and 24/7 uninterrupted operation capability. In this way, it can be quickly integrated into different projects and provides great convenience to the user in planning and maintenance processes.

Technical Advantages of WMU Series Wall Mounted Industrial Type Air Conditioners Units Compared to Competitors

In industrial air conditioners systems, not only the initial cost but also environmental durability, control infrastructure, energy efficiency and integration capability are of great importance. WMU Series Wall Mounted Industrial Type Air Conditioners Units stand out with their powerful features that distinguish them from their competitors in these areas.

• Wide Temperature Range: Operating from -25°C to +60°C, WMU series wall-mounted air conditioners adapt to all conditions, from inside factories to mine sites, from open space containers to cold climate zones. Competitor devices are mostly limited to -10°C to +48°C.
• 48VDC Emergency Cooling: This feature, which maintains basic cooling with low voltage during power outages, is often not available in competitive systems or requires special ordering.
• Centralised Management: WMU Series Wall Mounted Industrial Type Air Conditioners Units are fully compatible with automation setups in large facilities with its central control feature up to 12 devices. It offers critical advantages such as load sharing and system continuity in case of failure.
• Wide Communication Support: It easily integrates into SCADA and BMS systems with Modbus, Ethernet and GSM protocols. Most competitors only work with Modbus RTU.
