Manufacturers of coolers and freezers are staying cool in the face of regulations that have forced them into a temporary holding pattern. 

The Tenant Star program will give tenants and building owners a way to work together to achieve significant energy savings in leased commercial spaces.

Now celebrating its 50^th anniversary, the company has expanded over the years to include HVAC, electrical, pest control, home security, and plenty of other services.

The benefits of portables, including speedy implementation, reduced downtime, and cost-effectiveness, are continuing to gain recognition from end users. And, as end users experience these benefits and the resulting uptime, industry experts expect the portable market to continue to heat up.

The 92 percent proposed standard is just one of the DOE’s rulemakings to be challenged recently by stakeholders, and it’s unlikely to be the last. 

Keeping people happy and cool isn’t always easy in a crunch, so it’s essential commercial contractors have the right practices in place — including access to portable equipment — to quickly restore cooling in emergency situations.

Since they don’t have to stay in one place, portable cooling units have been known to show up in some pretty unique places. Here’s a closer look at how portable units are serving in some outside-the-box applications.

If refrigerant migration occurs in a system that has a crankcase heater, the vapor will be forced away from the crankcase and end up in the suction line. This refrigerant may condense in the suction line and cause slugging in the compressor’s cylinders on startup. 

Thinking in temperature in-stead of pressure can help make the crossover to a new refrigerant much easier. The next time you’re faced with determining the correct operating evaporator or condensing pressure, think in terms of temperature and then convert it to pressure.

The plan that emerged from the Chemical Facility Safety and Security Working Group includes improved coordination and information sharing across DHS, OSHA, and the EPA as well as better coordination with state and local officials including the first-response community.
