Alpine E.E.C.
For cabinets and enclosures in extreme environments
The Alpine has been designed to alleviate the effects of extreme temperature on electronic equipment – and more importantly batteries.
It provides ventilation to minimise hydrogen accumulation and allows uncontaminated air to cool equipment when the desired temperature is exceeded.
External vents are fitted with rain hoods and filters to protect against weather, dust and insects. The upper vent allows ventilation to prevent hydrogen build up.
Ventech recommends the use of Polyester or Polycarbonate enclosures or cabinets depending on specific installation requirements and environmental conditions.
The Alpine is suited to remote alternative-powered sites, including solar and wind generation, providing an efficient, eco-friendly, solution.
Ideal for:
Remote cell sites - Airport runways - Traffic Lights - Weather Tracking Stations - Lighthouses - Security Systems - Basements - Roof Tops - Car Parks
Features:
Test Results 30W Heat Load
With a heat load of 30 watts being produced by electronic equipment in the equipment cabinet located in the main cabinet and the venting thermostat set to operate 25°C (TSET), the operational temperature shape of the cabinet is clear and it is possible to read off key performance parameters.
The green line highlights where the 30 watts of heat generated by the electronic equipment maintains the protected temperature (TP) regard less of the ambient temperature. TMAX 22.2°C, TMIN -25.7°C giving a 
T5 of 47.9°C where TP is constant.
The red line shows where the cabinet is unable to regulate heat as the ambient temperature increases near to or above TP. Along the blue line the heat being generated in the equipment cabinet is insufficient to maintain TP.
Test Results 50W Heat Load
When the venting system is rejecting heat in the equipment cabinet, the warm air being expelled is passed over the batteries before being ejected from the main cabinet. This raises the battery temperature well above ambient temperature and with the addition of a foam insulating blanket over the batteries a further temperature gain is realised therefore increasing their discharge performance.
The black dotted line tracks TAMBIENT and TCABINET as if there were no restrictions to heating or cooling.
Insulation
Cabinets are insulated with a thermal insulation material made from Polysafe, an environmentally friendly polyolefin foam, to control heat loss, prevent condensation, to reduce noise and vibration.
External Vents
External vents are fitted with rain hoods and filters to protect against weather, dust and insects. The upper vent allows ventilation to prevent hydrogen build up.
Cabinets
Ventech recommends the use of Polyester or Polycarbonate enclosures or cabinets depending on specific installation requirements and environmental conditions.
Ideal Locations
Remote Cell Sites - Airport Runways - Traffic Lights - Weather Tracking Stations - Lighthouses - Security Systems - Basements - Roof Tops - Car Parks
Security
The outer cabinet is accessed by key entry and has no external screws or fittings. This provides a secure environment for your equipment.
