  • Oil is leaking from my rear oil seal on my ZA ZR ZT ZE compressor what could be the cause ?
    Check your breather is operating normally and the filter on your breather has been replaced Your HP LP elements could be surpassing there lifetime and the air seals are passing air pressure from the LP or HP elements into your gearbox causing higher than normal crankcase pressure. For more information diagnosing this fault contact Ztechnique for a consultation.
  • My Atlas Copco ZR ZT High oil temperature from HP LP oil returns to sump ? what could be the cause
    If you have abnormal oil temperature from both your HP LP oil returns and higher than normal LP HP element temps check: •Check the oil temperature is it in normal range •Check oil is in the gearbox is filled to normal levels •Replace oil filter and check contents of filter for debris •Check the oil cooler (water) Delta T is normal across the cooler if not suspect a blockage •If all above ok look further at mechanical components SERVICE TIP – On modern ZR ZT the Alfa Laval oil coolers are very hard to clean – we recommend replace the cooler
  • My Intercooler pressure is higher than normal ? what could it be ?
    Generally if you have high intercooler pressure on an Atlas Copco 2 stage oil free Z compressor its most likely to be your High Pressure element failing. Take the Elektronikon readings from the panel for LP out , HP in, HP Out. A failing HP element will normally create a higher than normal air temperature from your Low Pressure element in the range of 190 to 230 c and could trip the compressor as the Intercooler reaches 47 psi maximum allowable pressure. If your having issues with your Z compressor you can contact us using the form below and we can action a Teams call between us.
  • The Intercooler pressure is lower than normal 1.9 bar what could be the cause
    If you have the following operating conditions its Is likely that your LP Element is failing . •Low Intercooler pressure under 1.9 bar •Normal LP Element Outlet Temperature 150 /170’c •High HP element outlet temperature 180/200+’c •HP Inlet Normal temp 45 to 50’c typical You can also check for leakage on your intercooler circuit which can also lower intercooler pressure. If you need assistance contact Ztechnique now for a discussion on next steps

  • My compressor has High LP Element Temp ZR ZT off loaded ? what could cause that
    If you have abnormal intercooler vacuum and your LP element outlet is hotter than normal check the following •Your vacuum cannot be adjusted by the intercooler screw . It remains constant no difference •Your LP element is running hot off load and trips @ 220’c •Your Intercooler pressure is lower than 1.9 bar SERVICE TIP – Check intercooler circuit on/off load for leaks _ More prone on ZT compressor circuits.
  • High HP Element Temperatures ZR ZT On Load ? what could be the cause
    •LP Outlet temp 150 to 170’c typical normal running •HP Inlet temp if over 60’c intercooler probably blocked water or air side •High HP element outlet temperature 180/200+’c SERVICE TIP – Check cooler condition external and internally before other invasive checks
  • My MD dryer has covered 40,000 hours run and isn't performing well
    Most MD dryers can surpass 40,000 hours run in ideal environment conditions. However many MD dryers simply don't get the required attention they need over the 40,000 hours use and suffer from premature failure of the drum material. If your suffering lower and lower dewpoint and your dryer is over 40,000 hours run it needs a full overhaul that includes a new drum and all the ancillary parts that the manufacturer states are required. Ztechnique can provide a new or refurbished MD drum and all necessary spare parts to bring your MD dryer back to its full dewpoint capability at a significantly less cost than the OEM prices All our work is guaranteed. If you need assistance with a failing Atlas Copco MD dryer, contact us now and we can assist you wherever you are in the World
  • Heat Recovery what benefits does it have for my MD dryer
    Often Atlas Copco MD dryers are operating outside of there ideal design range and the regen drum can become saturated with moisture. One solution is to retrofit a 'low load heater' to the dryer enabling the dryer regen temperature to be maintained above 125 c when the compressor is off load. Ztechnique can offer a retrofit kit to correct the low dewpoint situation. Please inquire about this service directly with our support team
  • My MD dryer has stopped its drum rotation ? what could be causing that
    Check the motor is turning on load by observing the motor fan turning The rotate signal to turn from the Z compressor could be faulty and the motor is not turning The compressor could be unloaded There could be internal damage to the gearbox drive coupling (sheared off ) and the drum has stopped rotating internally. Remove the MD dryer lid to check
  • The Delta T across my water in/out of my Regen cooler is the same ? what is the problem
    Check that your water is flowing in and out of the regen cooler If you have good water supply the next steps is to see if the cooler is blocked by removing the water inlet cap and checking the face of the tubes for water blockages. Action: clean the water tubes with threaded rod by pushing the thread rod inside and out of the tubes the entire length of the cooler top clear loose material. If you meet with resistance remove the cooler for specialised cleaning.
  • My Dewpoint is below -20 on my Atlas Copco MD dryer what may be the cause
    Atlas Copco MD IMD dryers rely heavily on a number of factors to ensure the dryer can reach -20 dewpoint. Tuning of the dryer is very important and needs adjustment generally every 2000 hours of service Regular services each year. The 8000 hour service is very important that the Demister pad is replaced inside the dryer Drum saturation levels can be affected by poor load unload cycles Too low of a regen temperature from the Z compressor keeps the drum too wet and the result is poor dewpoint. Moisture drains have to be functioning 100% Regen cooler temperature is critical and can be affected by poor water conditions (temp) and tube clogging If your MD dryer isn't performing to your expectations contact us for a teams call and we can usally detect the problem for you with a few checks you can make yourself.
  • I have lowered my site air pressure to 5 bar what impact will this have on my MD Dryer
    Lowering your site air pressure lower than the deign pressure of your Atlas Copco MD dryer will effect its Dewpoint performance. MD dryers are normally sold for 7 bar air pressure applications unless otherwise specified. The regen air nozzle inside the dryer is sized specifically for 7 bar pressure. If you lower the pressure too low the effectiveness of the regen air will make the dryer unstable and the result will be lower dewpoint of the dryer. You must change the nozzle for a smaller size to increase the velocity of the regen air. A list of nozzle sizes are provided on the side of your MD dryer. You can obtain alternative nozzles from Ztechnique
  • My differential setting needs adjustment on my MD dryer ? what should the correct adjustment be.
    If you check your DP on your MD dryer and its giving a larger than normal reading 'compressor on load' you can adjust your regen valve to bring the MD dryer WG reading back in line with the settings below. make small adjustments to the regen valve and always ensure the water gauge reading is higher on the left of the DP gauge when checking it as per the image below. Be careful adjusting the regen valve when the compressor is running as the regen valve can be 150c temperature or more and can cause burns. The compressor must be up to normal temperature and on load to set the DP. If your in doubt how to set the DP we can arrange to provide you with online training from our Ztechnique facility. This is a chargeable training service. For more information contact ztechnique Fixed Speed MD dryers: Set DP at 15-30 mmWG VSD dryers: Set DP at 10-15 mmWG at minimum speed of the compressor/dryer
