View BioLogic™ Touchscreen

BioCold environmental rooms and chambers offer a number of standard features and customer options which set our product apart from the competition. Using the latest in available technology, these features provide our customers with user-friendly, energy-efficient, and highly reliable environmental solutions. The information below highlights several of the most important features which make our chambers unique.

NEW!!! BioLogic™ touchscreen interface:
Touchscreen chamber controls represent the next generation in environmental chamber operation. BioCold has recently introduced its new BioLogic™ touchscreen user interface, standard on all stability test chambers. Paired with a multiloop PID process controller with logic functionality, the BioLogic™ HMI (human machine interface) offers a fully-validatable package for FDA-regulated applications, including data encryption, password protected access, and 21 CFR Part 11 compliant data a cquisition and storage. An 8" full-color display, Windows CE and full-featured communications package (USB/Ethernet/COM) permits 24/7 local and remote (including online) access to chamber data and operations.

Thermoelectric Cooling:
Used exclusively on our stability test chambers, thermoelectric (Peltier) air-to-air heat exchangers provide a quiet, efficient solution for chambers operating at near-ambient conditions. Over their 20-plus year lifetime, thermoelectric heat exchangers save hundreds of dollars in utility and repair costs compared to traditional refrigeration systems. NOTE: Because of their limited cooling capacity of approximately 600 BTUH, thermoelectric heat exchangers may be used on solid door chambers at 20�C and above, or on glass door chambers at temperatures of 25�C and above.

Dehumidification:
Dessicant dehumidifiers offer a virtually maintenance-free solution for reduced humidity applications to 20% RH. Dehumidification can be added to most of our chamber models.

Brushless DC Fan Motors:
Effective January 1, 2008, California Energy Commission regulations will require brushless DC (electronically commutated) fan motors on all walk-in cooler and freezer equipment. In addition to complying with the California efficiency regulations on walk-in coolers and freezers, BioCold has shifted to use of electronically commutated motors on its stability chamber series as well, increasing energy efficiency well above the California requirements for reach-in chambers. BioCold's custom designed electronically commutated fan motors provide high-volume airflow for maximum chamber uniformity, while still maintaining 80% energy efficiency, a 50% increase over traditional shaded pole motors (and 30% better than PSC motors).

Ultrasonic Humidification:
Standard on many models, BioCold uses an ultrasonic vapor generator to achieve chamber humidity levels up to 85% RH. Unlike steam boilers, ultrasonic humidification offers the ability to control humidity control without simultaneously adding heat to the chamber. Additionally, ultrasonic transducers can be pulsed on/off rapidly, providing extraordinarily close control.
