“Don’t Ever Promise More Than You Can Deliver But Always Deliver More than You Promise – Lou Holtz”




“Don’t Ever Promise More Than You Can Deliver But Always Deliver More than You Promise – Lou Holtz”





RAB Specialist Engineers were recently asked to install external filtration on two TCI (Transtherm Cooling Industries) horizontal coolers for the Frimley Health NHS Foundation Trust.  

The initial survey concentrated on the measurement and design of a RABΞScreen filter to protect the downward facing coils. However, upon closer inspection, we saw that the coils had become heavily compacted with debris including pollen, seed and leaves. 


There is little point in fitting a coil protecting RABΞScreen when the damage has already been done and we agreed that our installer would clean the coils before fitting the purpose made external filter. 

A factory order was issued for the new RABΞScreens and two weeks later they were ready to fit. 

One of the coolers was cleaned, checked and then had its filter installed. 

The other was cleaned, checked and found to have a problem with compressor #2 which was tripping out on low pressure due to a leak on the condenser baffle.  

We returned with two new drier cores to fix the problem and fitted RABΞScreens to a fully functioning chiller. 

Discharge pressure dropped from 19.5BAR with fans on full load to only 15BAR with fans regulating. 


Lower discharge pressure + correct fan operation = £5,000 reduced energy cost for Wexham Park Hospital. 

If you use a professional to complete your installation you will always be able to go that extra mile for the customer.  In this case fully repaired equipment, totally cleaned and protected from further contamination.

Lou Holtz would be proud of the RABSE team. We always over deliver.
