Planned Maintenance for Scientific Refrigeration Equipment

In addition to our maintenance programs on Refrigeration and HVAC equipment, we also provide maintenance programs for Scientific Refrigeration equipment that follows the following standards.


The term validation is often misused and misunderstood. Validations need to follow FDA & AABB standards. The definition of equipment validation is broken down into three sections:

  1. IQ – Installation Qualification. This is a very simple document that provides proof that the equipment was installed correctly and fully operational.
  2. OQ – Operational Qualification. This document provides proof that the equipment is performing correctly and performance meets the material requirements. A 24 hour temperature map of an empty chamber is part of this document.
  3. PQ – Product Qualification. This document provides proof that the equipment maintains the material within stated tolerance. A 24 hour temperature map of a loaded chamber is documented along with an open door study and power failure study.

We have performed validations for many QA/QC managers and are willing to provide any one of the above validation steps to assist in your validation as well.
