Ben-Hur was on the big screen, Frank Sinatra was top of the pops, Xerox launched the first commercial photocopier and KeepRite Refrigeration introduced an evolutionary refrigeration control system known as Limitrol.

The 50’s and 60’s were a time of cultural revolution and technical innovation. KeepRite Refrigeration’s development of the original Limitrol in 1959 was a ground-breaking system that would be used in 1000’s of refrigeration systems around the world and for over 50 years.

2014 marks another milestone year for KeepRite Refrigeration and a complete reinvention of the control system that helped establish KeepRite Refrigeration as an industry leader.

Introducing Limitrol+, a major leap forward in commercial refrigeration.

“Conventional head pressure control systems maintain a constant head pressure regardless of ambient temperatures. Limitrol+ intelligently responds to ambient conditions to float head pressure without sacrificing system performance at lower temperatures.”

Vince Zolli, KeepRite Refrigeration’s Head of Engineering and leader of the Limitrol+ development team says the new system is fundamentally different from previous systems.

“Limitrol+ functions in much colder ambient environments where previous systems have proven ineffective in eliminating the concept of condenser flooding.”

So how does Limitrol+ work?

Essentially Limitrol+ combines a variety of modern technologies into a responsive system that floats head pressure. The result is a system that saves energy and substantially reduces environmental impact through reduced refrigerant use.

KeepRite Refrigeration’s Marketing & Customer Service Manager Tim Charlick says Limitrol+ has a distinct advantage over competitive systems.

“Unlike competitive systems, Limitrol+ combines variable speed EC motor technology, condenser portioning and various systems modifications to provide the ultimate combination of performance and control.”

Limitrol+ is ideally suited for and most effective in environments with fluctuating ambient temperatures. Suitable for condensing units over 5 HP, Limitrol+ is perfect for installations where reduced refrigerant charges are desired or required.

Already implemented across a variety of KeepRite Refrigeration products, the KeepRite Refrigeration team believe that patent-pending Limitrol+ is a game changing system that will continue to drive their industry leading company towards a broader customer base and greater market share.

Limitrol+ is part of KeepRite Refrigeration’s Smart3 group – a suite of KeepRite Refrigeration technical innovations that reduce operating costs, reduce environmental impact and deliver more for less.
