Refrigerant Feature
A future-proof solution with A2L category refrigerants
THE BITZER ECOLITE 2.0 series of condensing units are set to be released in the third quarter of 2020 with refrigerants in the safety group A2L which includes R1234ze/yf, R455A and R454C.
The ECOLITE 2.0 series of condensing units have new functions inside the controller includ- ing the oil return function. First field test units have already been shipped; further ones are available on request.
ECOLITE condensing units open up a wide range of applications from 1.5 kW to 5 kW in the low temperature range and from 3.5 kW to 16 kW in the medium temperature range.
One of their great advantages: Each of the sev- en models can be used for different applications and various refrigerants.
The new ECOLITE version for low-GWP refrig- erants of the A2L category offers a future-proof solution for refrigerants with a GWP below 150.
The design of the condensing units ensures that their components are comfortably accessible and can be serviced quickly and easily if necessary.
With all ECOLITE models, users enjoy the op- tion of quick installation and commissioning thanks to the user-friendly controller with a dis- play and connectivity to the BEST software.
All models in the series have been designed as standard for a wide range of both low and me- dium temperature applications – for example in cold stores, petrol stations and small shops.
Its compact and low-sound design offers
the opportunity to install the ECOLITE both in urban and rural areas. Furthermore, the semi-hermetic ECOLINE compressor equipped with the mechanical capacity con- trol VARISTEP makes the unit exceptionally flexible and reliable.
BITZER recently won the German 2020 HVACR trust award in the condensing units
category for the second time in a row. At this award, industry representatives such as con- tractors, expert planners and operators of re- frigeration systems vote for products and their manufacturers in 14 different categories with- in refrigeration and air-conditioning technolo- gy, ventilation and air ducting as well as build- ing automation and fire.
Not all sealants are created equal
Systems installed today are much better maintained.

LEAKAGE RATES FROM systems installed in Australia have dropped from 30% in the year 1990 to 6% today, according to Refrigerant Re- claim Australia (RRA).
Speaking to participants at CCN Live 2019, RRA’s Michael Bennett, said back in 1990 90% of emissions came from leaking R12.
“These days split systems leak less than 1% and stationary systems 3-4% which is a remark- able achievement,” he said
“This can be attributed to a range of factors from better design and improved maintenance to greater awareness and training.”
The bank of refrigerant in Australia today is five times larger than it was in 1990.
Products also play a part in reduced leaks but not all sealants are created equal, according to Rectorseal’s Craig Bickett.
“Products with polymers are reactive when combined with moisture and air. Non-polymer refrigerant leak sealant does not react and won’t clog the air-conditioning system,” he said.
“To extend the unit life of your clients’ older, out- of-warranty air-conditioning, an oil-based refrig- erant leak sealant such as RectorSeal’s AC Leak Freeze PRO with Nano particles is the best choice.”
The AC Leak Freeze PRO now includes the new Mini Split AC Leak Freeze PRO offering the PRO and the UV PRO for added convenience.
It is available at all leading HVAC stores.
