99% efficiency of oil separation

The High Efficiency Oil Separator features a centrifugal flow path achieving approximately 99% efficiency of oil separation with low pressure drop. Testing by an independent laboratory found that only 0.006% oil by volume was being discharged into the system after leaving a HE oil separator. Virtually oil-free refrigerant gas exists through a fitting just below the lower edge of the oil separator.

Replaceable filter drier blocks and filter cores with STAS

To prevent contamination, do not open can until ready to install.
  1. Pump down the system and the STAS completely. Warning: System lines must be de-pressurized before attempting to service. Failure to do so can result in system damage and serious bodily injury.
  2. Remove the cover bolts, cover, and cover gasket (discard old gasket).
  3. Withdraw the internal assembly by pulling on the handle.
  4. Disassemble the internal assembly by unscrewing the handle while holding the inlet retainer.
  5. Remove contaminated filter-drier block. For multiple block units, remove couplings.
  6. Clean all internal parts thoroughly, giving particular care and attention to outlet screen.
  7. Remove the block from can and reassemble as rapidly as possible to minimize moisture contamination.
  8. Replace the screen in the outlet retainer and install the new block or core in the outlet retainer. Make certain that the end of the block with the tapered inside diameter is placed against the outlet retainer. With multiple block units, place coupling between each block or core. Position the inlet retainer over the final block or core, and screw the handle firmly in place. Carefully insert the assembled unit into the shell assembly.
  9. Lightly coat the new cover gasket with refrigeration oil on both surfaces and carefully place in the groove of the cover.
  10. Push the cover against the shell assembly. Make certain that the compression spring is against the inlet retainer, and is not handing up on the handle.
  11. Install 2 cover bolts diagonally opposite holes to hold the cover snugly against the shell edge. Install the remaining bolts snugly.
  12. Torque all cover bolts evenly in a criss-cross pattern to a torque of 25ft. lbs. maximum for STAS units. For stainless steel bolts in SV series suction line service, the maximum torque is 20ft.lbs.
  13. Test for leakage.

TIR, TER, THR, TMR, ZZ, TRAE, XC-726 Thermal Expansion Valve Customers

Prior to May 28, 2007 production, the power assemblies of the above models were manufactured with a yellow dichromate coating for corrosion protection. While the Cr+6 in the coating is within acceptable levels for compliance with the Restriction of Hazardous Substances (RoHS) international directive, Emerson has elected to change to a plating process completely free of Cr+6.
On May 28, 2007, production will change from the yellow dichromate coating to a silver-blue zinc plating. This plating is also in compliance with RoHS.

This change will not affect the fit, form, or function of the models, including corrosion protection. The change is detectable by the visual appearance difference noted.

Trouble shooting a TXV

Many expansion valves are returned to their manufacturers due to a perceived malfunction, but in reality the problem is in the system, not the valve. [More]

Liquid must be going to the TXV in order for the valve to work properly. If the line contains too much vapor, that could be causing the valve’s apparent malfunction.

One valve for ALL applications

The EX electrical control valve can be used in different control tasks.

  • expansion valve for superheat control
  • suction pressure control for capacity control
  • liquid injection for desuperheating of compressor
  • condensing pressure control
  • hot-gas bypass control to compensate excess compressor capacity and to ensure evaporating pressure does not go below a set point.

The ideal mounting position of control valves is with motor downward.

How to choose a reliable Alco Controls reseller?

1) The reseller should be an Alco Controls oriented store.
2) The reseller should have a reasonably good knowledge of their products that will answer your questions regarding size selections, installations, trouble-shooting and certainly help you make a wise purchase.
3) If you stick to a reseller that is really an Alco Controls oriented store, that is totally focusing on Alco, you have a better chance of ensuring what the sales staff are talking about. If a store specializes in 20-30 different things, how good are they in any one of those things? But you come into a store that specializes in 1-2 things, you have a better chance of getting the correct products for your job. Refrigeration applications are different. That’s why we focus on giving you the right components ~ selected for specific application. With us value isn't just how much you save, but how much more you receive!

Differential Pressure Controls Series

FD113 oil pressure safety control senses the effective oil pressure on pressure lubricate compressors. If inadequate oil pressure exists, a time delay is energized. If oil pressure does not recover to safe levels within the time delay setting, the compressor is shut down. The time delay allows the compressor adequate time to establish oil pressure on start up and avoids nuisance shutdowns on pressure drop of short duration during the run cycle.
FD113 uses the pressure differential between the 2 inputs to operate and electrical switch. For application in refrigeration and air-conditioning systems according to EN378. Compressor oil pressure control.
Maximum application flexibility is assured by providing an adjustable differential pressure switch which can be adjusted to the compressor's minimum required oil pressure needs and an adjustable electronic time delay which allows you to select the length of time the compressor runs below the minimum pressure before shutdown.
The minimum pressure setting and time delay values specified by the compressor manufacturer should be used when installing the FD113 control.

  1. Pressure range adjustable from 4 to 65 psid; timer start pressure - timer stop pressure is 3psid above timer start pressure.
  2. A SPDT switch is used in the pressure portion of the control which allows the addition of a 'safe-light' is desired.
  3. Electronic timer is time-adjustable from 20 to 150 seconds, supply voltage - 24 to 240Volt AC/DC; timing unaffected by voltage or ambient temperature variations.
  4. A SPDT manual reset switch is used in the timer module; upon time-out, the compressor is stopped and an alarm circuit is energized; to restart the compressor and de-energize the alarm circuit, the reset button is pushed.
  5. A factory installed jumper allowed the FD113 to be powered from a single source power; should separate circuits be desired for the timer and 'lockout' switch, the jumper can be removed.
  6. Agency approvals include: UL/CUL file number E85974, VDE0631/0660, Tuv, CE73/23/EWG, CE93/68/EWG.
