Controlled Conditions provides installation, calibration and maintenance for a variety of medical equipment.

  • For customers such as plasma centers, donor organ storage facilities and laboratories, we provide maintenance of freezers (walk-in, cascade & LN2), incubators, centrifuges, fume hoods and heat blocks. Some of these freezers operate at minus 80 degrees centigrade and have recorders and alarm systems for which we are authorized service representatives.
  • Controlled Conditions also maintains standards traceable to NIST for the calibration of temperature measuring devices and other related calibrations such as RPM, pressure, air velocities, etc.
  • Our staff has participated in design and certification of clean room installations.
