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

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.

Extreme Equipment Cabinet
Open State
In warm conditions or when heat generated by electronics is high, the EC allows air to flow in via the lower external vent and pass through the control assembly and into the internal cabinet which houses electronics. Warm air moves via the fan through ducting and is passed over the batteries before leaving the EC via the upper vent.
Closed State
When cooler internal cabinet temperatures are experienced through ambient air or equipment load reduction, the EC control unit closes allowing remaining component heat to be contained providing desired conditions for maximum battery output and life.
Circulation eliminates component hot spots and provides a true cabinet temperature for control thermostats or monitoring equipment.
