It’s a common winter woe affecting thousands of building owners and managers each year: frozen water pipes that burst.

To prepare you for this month’s troubleshooting situation … you’re not the first technician to be called, nor are you the second technician.

Bob and Tim have arrived at the apartment house that they have been working at for the last several days. They’ve gone to the roof where the outdoor units are located. There are 60 heat pumps that use R-22 as the refrigerant. They start with Unit No. 2.
It is important to understand grease extraction and new options in capturing grease particulate efficiently near the source. A commonly overlooked byproduct of many cooking processes is grease — overlooked, that is, until it causes problems at a restaurant facility.
