Dehydrated - Import export

For anyone intending to carry out routine maintenance to critical pressurisation units, the 12377 is an essential tool. Weighing approximately 30kg this unit is fully portable. Its design incorporates wheels, and an extendable handle to aid its movement. Following a recent design change to incorporate the same 1/3HP compressor that is used in the 12434, and 12437, this small unit is now able to produce a dry air output of 30 cubic feet per hour at output pressures of between 3 and 15 psi. Should increase flow be required a unique feature allows a second compressor to be connected to a built-in power take off point. Each 12377 is supplied ready to run, complete with 3 metre power lead and plug, and a quick connect chuck for pneumatic connection. Uses twin tower molecular sieve, adsorption system.

Closely matched with the performance and specifications of our accomplished 19” rack-mounting waveguide dehydrators, the 12445 series Waveguide Dehydrator is intended to offer our customers a range of space-saving wall-mounting alternatives. Now available with 3 levels of performance, the 12445 range suits many applications. Protruding only 16cm or 23cm from a wall, and mounting via integral keyhole slots, these units dispense with any need for additional shelving or brackets. In addition to the exceptional performance now associated with Drallim Waveguide Dehydrators, in this case between 5 and 35 cubic feet per hour output, the 12445s are loaded with features, including the following: Integral air reservoir Adjustable output pressure regulator Output flow meter Humidity detection equipment Excessive run-time alarm Remote alarm monitoring terminal Digital runtime display High and low output pressure alarms

The 12437 Waveguide Dehydrator, designed for cable pressurisation applications, has proved successful in numerous aerial and waveguide applications, and a low-pressure version has evolved. This unit is the same as its higher-pressure counterpart, but for an output regulator, and gauge which are more accurate within the 0.5 to 3 p.s.i. pressure band. This dehydrator uses an efficient 1/3 HP compressor to fill its large integral receiver to a pressure of up to 65 p.s.i. In addition, to the larger receiver, the unit benefits from built in compressor and receiver gauges. These gauges can help the operator to assess the condition of a unit, and help with fault finding in the event of a failure. Another useful feature of this unit is the humidity detector test facility, which assists in fault analysis alongside the standard remote alarms. In common with all our current units, the 12437 Waveguide Dehydrator is equipped with a thermal/magnetic overload circuit breaker with neon indicator.

The Drallim Dehydrator type 12269 is an energy saving integrated unit for supplying low pressure dry air to, for example, telephone cables, waveguides and aerial feeders. Design emphasis is on reliability and low maintenance given the critical role of this unit within an operator’s system. These products provide a continuous supply for dried air, at pressure, to maintain the operational integrity of cable systems and broadcast transmitter feeds. This very high-performance unit is home to two 3/4HP compressors. This unit can produce more than 185 cubic feet per hour, this is regulated and split between up to 80 outlets, each with its own flowmeter for a visual indication of each cables demand for air. Mains Failure, High Humidity, Low Output Pressure, High Output Pressure, Compressor 1 and 2 Duty indicator. It’s low noise level of around 60dBA is quiet enough to allow it to be sited in manned areas.

The waveguide dehydrator is a crucial element of any communications waveguide system, be it a microwave, radar, TV satellite terrestrial or antenna system. This high-capacity waveguide dehydrator for location in both ETSI and standard 19” racks, has reversible mounting brackets allowing the same unit to fit within either enclosure without any further need for mounting brackets or plates. Whether you choose the 230vAC or the 48vDC variant, the 12446 boasts an impressive output of over 220 litres per hour at an excellent dewpoint of -40ºC. The unit comes with 2 fixed output pressure options of either 15 or 40 mbar, and 6 off ¼” pneumatic outlets as standard. Despite its physical dimensions, the 12446 houses a high capacity, high pressure air storage vessel which allows the unit to remain inactive for extended periods of time, keeping maintenance requirements to an absolute minimum. Dry air delivery: 8 ft3/hr Dry air dew point -40c Output pressure 0.2 – 6 psi
