Bob and Tim were getting set up to clean the condenser tubes in a chiller. They were doing this job at night during overtime hours because they discovered the problem earlier that afternoon and the customer said the chiller needed to be able to operate at full capacity tomorrow for a conference.
Bob and Tim were on their way to a no cooling call at an office building with a 100-ton water-cooled chiller. As always, management was in a hurry to get the problem solved because the tenants were hot.
When it comes to large equipment that powers HVAC systems, the old saying “an ounce of prevention is worth a pound of cure” definitely rings true. And nowhere is an ounce of prevention more beneficial than with chiller maintenance.
