Evaporative fluid cooler

New fluid coolers to be available in Q4 2016


Jumbo Cooler fluid coolers are intended for cooling process water in industrial, commercial, and free cooling applications, and features the benefits of evaporative cooling with water recirculation, thus minimizing energy and water consumption and offer increasing free cooling hours.

Jumbo Cooler units are equipped with evaporative pads wetted via the water distribution system to pre-cool the air before passing through the heat exchanger coils. This increases the amount of heat the air can extract from the coil and, in turn, increases the cooling capacity of the unit.

Microchannel evaporator

Advanced microchannel technology for HVAC and process cooling


The HVAC and process industries are making a transition to microchannel heat exchangers. This is evidenced by the extensive use of microchannel condensers by major HVAC manufacturers and many smaller OEMs manufacturing cooling and refrigeration equipment. Significant energy efficiency improvements drive the trend, the need for smaller equipment footprints and weight, conversion to lower GWP refrigerants, and the ongoing rise in the cost of copper.

Methods of microchannel coils defrosting


Microchannel coils are becoming quite popular as an alternative to bulky finned tube heat exchangers. For the desired capacity, microchannel coils are smaller in size resulting in less refrigerant charge in the system, offer higher heat transfer performance, and lower weight. However, until now, microchannel coils used only to a very limited extent in HVAC units exposed to freezing conditions like heat pumps.

Air-cooled chiller

V-shaped microchannel coils for chiller applications


The efficiency of air-cooled chiller is dictated by the condensing temperature, which may be decreased with increasing heat transfer performance of the condensing coil. Microchannel heat exchangers have become popular in chiller applications due to better thermo-hydraulic characteristics in comparison to conventional finned tube heat exchanger designs. The most straightforward way to improve heat exchanger performance is to increase its face area by combining two microchannel coils in V form.

Microchannel coils add dimension for cooling systems



by Steven Wand

Although not traditionally used in industrial process applications, microchannel designs may offer advantages over traditional coil technologies in most process cooling applications. Long considered a coil technology primarily used in commercial and residential air-conditioning, microchannel coils are being used by more manufacturers who have discovered how they can improve process cooling applications.

Microchannel coil: fix or replace


by Lance Robinson

I vote for fix. Anytime you can fix a condenser as opposed to replacing it, is a good day for all in the repair business. Less time = more money. Customers are happier and all around better vibe. Replacement of perfectly good coil makes no sense. Instead make the fix in less than 5 minutes with a propane torch and a few simple instruments all HVAC techs have on hand.
