Mark Key, vice president, sales and marketing, Redi Controls, believes the company's purger is top-notch. "Every time a service technician has to respond to a chiller that is needing assistance due to lost capacity [oil migration], that decreases the profit on that service contract," wrote Key in his entry form.

"This product can be sold to the customer (and energy management departments often assist with funding), save the customer thousands of dollars in energy savings, and thus the Industrial OAM-Purger pays for itself, and the service contractor regains capacity and decreases the amount of time servicing this chiller, thus increasing profits on the service contract."
