Automatic Drain Valve For Air Compressor

Condensate drains remove condensate separated in centrifugal separators, air receivers, refrigerated dryers and filters from the compressed air system. In particular, if the timer has timed out, and the temperature representative of the steam temperature at the source is greater than the header setpoint temperature THDR, or if the difference in temperature between the steam temperature at the source and steam temperature at the drain is less than the steam setpoint temperature, TSP, relay contact K2 is opened and relay contact K1 is closed.
Filter bowl floats seem to be more reliable than they used to be. Today some come with a built-in particulate screen to prevent small particles from getting condensate drain system stuck under the seat, but maybe the use of cleaner piping becoming more prevalent (copper, aluminum) has helped this drain type's reliability.

According to the Carson Dunlop training manual there are some limitations to inspecting your central air conditioning system, which are; you shouldn't test an air conditioner when the ambient air is below 65 degrees F or has been below 65 degrees in the past 24 hours, don't test if the power has been off for at least 12 to 24 hours because compressor could seize, most parts of air conditioner are not visible without removing plates etc which is beyond the scope of a home inspection and the interior cooling coil is normally not visible for inspection.
In particular, relay contact K2 closes and relay contact K1 opens when the first signal representative of the steam temperature at the source is less than the header setpoint temperature THDR, or when the difference in steam temperature between the source and drain, ΔT, is greater than or equal to the setpoint steam temperature, TSP.

The system of the present invention can be used to proportionally control the position of a modulating type of drain valve 24. For this purpose, line 76 is connected to line 40 for providing the signal representative of the difference in steam temperature between the source and drain, ΔT, through a dipswitch 78 to buffer amplifier unit 80. The output of the buffer amplifier unit 80 is provided along a line 82 and is an analog output proportional to the ΔT, and which would be used to proportionally control the position of a modulating type of drain valve 24.
With EC-Type Examination Certificate for use in explosive environments, these BEKOMAT condensate drains are approved for use in potentially explosive atmospheres condensate drain valve according to ll 2G Ex ib llB T4 Gb. THE BVS 03 ATEX W 124 certificate of confirmity approves the applicability for explosive hazardous areas.
Drainage ceases when the condensate level falls back to the minimum level. Our New Jersey Meter Condensate Traps give you a fully automatic and completely dependable condensate removal from compressor tanks (receivers); air systems; and industrial steam systems.

And gases, as well as main steam and waste steam, from compressed-air refrigeration vessels, storage vessels, and lowest points of air and steam lines, etc. Electronic timer drains are a very popular choice, easy to install, cost-effective and have a reliable operation when installed with an inlet strainer.
Depending on humidity and duty cycle, requirements for condensate discharge can be set and changed over time. Electronic sensor drains have few moving parts which ensure a reliable operation. When this difference in steam temperature is less than the temperature setpoint signal, the header has been sufficiently warmed and the drain valve control signal causes the drain valve to close.

It is designed as a robust condensate drain for water separators, filters or similar applications and can be used both in systems with oil-lubricated as well as with oil-free compressors. No. 4,135,542 Drain Device for Compressed Air Lines”, U.S. Pat. 2. In these drain valves, the float mechanism is not directly connected to the valve.
Condensate drains are possibly the least glamorous and most ignored component of a compressed air system but nevertheless, a most important part. Thus, for water at 212° F., the saturation pressure is 14.7 psia, and for water at 14.7 psia the saturation temperature is 212° F. If a substance exists as a liquid at the saturation temperature and pressure, it is called saturated liquid.
This float automates the process of condensate draining by opening and closing the valve after a certain amount of condensate is accumulated. ECO-DRAIN condensate drains are available for compressor flow rates up to 3500 cfm. We specialize in interconnection devices, electronic timers, proximity sensors, modules and specialty electronic devices.
