Description

The Kintronic Labs Model LAB4 dehydrator is set apart from the rest of the pack as a result of:

The LAB Series Technology

Unlike the older dehydrator technology, in which dehydrators are programmed to maintain pressure in the range between a low pressure and a high pressure setting, the LAB series dehydrators are programmed to maintain a single target pressure level. The unit is comprised of two alternating diaphragm pumps that are driven to operate below their maximum flow rate. While the first chamber is active, the desiccant in the second chamber is regenerated through heating and back-washing with a small reverse dry air flow. The pumps are controlled electronically by Pulse Width Modulation (PWM), supplying a flow rate equivalent to the real time leakage rate.

With the PWM control, there is an imperceptible vibration of the diaphragm pump. Maintaining the target pressure level eliminates the need for a pressure regulator, which means no pressure losses and an overall better response to flow regulation. Through this design, the dehydrator avoids the stress of continuously switching on at maximum speed and then switching off. Additionally, there are no mechanical parts in movement (except the diaphragm pumps) and no solenoid valves, thus reducing overall wear. The result is an increased MTBF and overall lifetime of the unit, as well as reduced noise and power consumption. As an added benefit, the PWM control also prevents a ripple in the pressure, thus increasing the stability of the dielectric constant properties of the air inside the transmission line.

Features:

1. Includes two pumps and two drying chambers running alternatively to yield an MTBF of > 165,000 hours
2. Drying chambers with automatic regeneration
3. Local and remote alarm signaling with optional remote control via SNMP protocol and HTTP interface by a 10/100 MB Ethernet interface
4. Optional digital flow meter for air flow measurement
5. Low power consumption and low acoustic noise
