First R290 Split system arrives for Real Alternatives Training
ECAC are proud to announce the arrival of the first Midea R290 Split System in Ireland for Real Alternatives Flammable Refrigerants Training. With a number of manufacturers aiming to enter the Market with Hydrocarbon based Split Systems ECAC has lead this move with the introduction of a Midea R290 Split Heat Pump. In conjunction with Real Alternatives we were able to source this system which is now set up in our training premises. Share On

ECAC Are Now the REAL Alternatives National Lead for Ireland
ECAC are proud to announce that we have been appointed the National Lead for REAL Alternatives for Ireland. REAL Alternatives 4 LIFE has built on the successful REAL Skills Europe & REAL Zero containment approaches. (Refrigerants, Emissions And Leakage – Zero). It was prepared by a consortium of Partners from across Europe, co-funded by the EU, included training and professional institutes as well as employer representative bodies. Share On
Live Online Courses
In response to Covid 19 we are developing a range of Live online short courses delivered via Zoom. Unlike many other training companies we believe that to gain the most from training it is important that our candidates have access to a live Tutor and have the opportunity to ask questions in real time.

Symptoms of non condensables (Air/Nitrogen) in system
High head pressures High Pressure trips High compressor head temperature Share On
Refrigerant overcharge symptoms
Head Pressures may be excessively high. There may also be excessive amounts of liquid stored in the condenser The condenser fan motor if on a control may run excessively or faster than Share On
Refrigerant under charge symptoms
Compressor run time excessive, Compressor thermal overload trip, Mechanical damage to compressor due to oil breakdown caused by excessive heat. Share On
Strength testing with OFN
The strength test procedure should comply with the recommendations listed in the European standard EN 378. The test pressure used should be between 1.1 and 1.43 times the allowable pressure depending on the PED category for that part of the system. The system may need to be divided into high and low sides for pressure testing purposes. This is required to ensure that the manufacturers test pressure applied to the low side, eg evaporator etc is not exceeded (particularly important on shell and tube evaporators using water). Share On

Annealing Copper
Working Copper tubing, bending, flaring, expanding etc. can be difficult if the copper is hard and brittle. It can lead to fracturing of the copper. By annealing the copper you can soften it to make it more workable and easier to bend. The process involves heating the copper to change its structure and allowing it to cool quickly. Share On
Vacuuming procedure
Checking your equipment On your gauge manifold inspect all seals, valves and connections and replace/repair as required Remove all of the old oil from your Vacuum pump, flush through with fresh oil and then recharge the pump with vac pump oil If necessary you can run the pump with the valve closed to warm the pump and oil up, drain and flush with fresh oil before again filling. To check the operation of the vacuum pump fit a calibrated vacuum gauge to the inlet and achieve the lowest pressure possible. Isolate the pump and watch for any rise in pressure. This may indicate a faulty pump or connection. Share On
The purpose of Evacuating a system
Vacuuming the system removes all traces of air, moisture and nitrogen that may be present in a system. Air and Nitrogen are non-condensable gasses which can cause high head pressures, high discharge temperatures, inefficient operation, high pressure trips and system failure. Share On
How to use a vacuum pressure temperature table
By using a vacuum pressure temperature table it is possible to determine the correct vacuum level you need to achieve to remove moisture and confirm that there is no moisture left in the system. Share On
Refrigerant Service Ban, January 2020
A service ban is now in place on the use of virgin refrigerants with a GWP over 2,500 . R404A and R507A along with R434A and R422D are affected. It is important to recognise that the ban is on the use of these refrigerants, not the purchase. This means that even if you are stocking virgin R404A for example, you cannot use it after 31st of December 2019. Share On
