An active cooling solution for small outdoor electronics and instrumentation equipment cabinets sited in hot climates has been launched by Intertec. The MULTICOOL 1100 cooler features a GRP (glass-reinforced polyester) housing that is inherently resistant to corrosion.
Offering 1100 W of cooling power, the product is a self-contained module that mounts directly on the outside wall of the equipment cabinet. It is especially suitable for cooling outdoor cabinets that are sited in hot and humid environments and wherever atmospheric contaminants such as salt, sulfur or carbon dioxide exacerbate metal corrosion.
There is no direct air path between the ambient environment and the inside of the equipment cabinet. The closed-loop refrigeration system has two completely separate and thermally isolated compartments: one for its evaporator, the other for the condenser and compressor stages. The evaporator is the only part of the system that is connected to the inside of the cabinet, via air ducts that are hermetically sealed to the cabinet walls, and employs fan-assisted air recirculation to maximise cooling performance. Heat is extracted from the cabinet by airflow over the evaporator and transported to the condenser via refrigerant gas. The condenser is cooled by its own separate fan, with the hot air and waste heat from the compressor being exhausted direct to atmosphere.
Suitable for use in ambient external temperatures from -20°C to 55°C, the cooler measures just 75 x 52 x 25 cm and weighs only 38 kg.
