Warminster, PA, January 2003 – Tescor, Inc. has recently designed and manufactured two Transportable Field-Conditioning Units for Redstone Arsenal. The TFCUs provide extreme high and low temperature environments to a standard test Chamber (TC) year round, unprotected in a temperate climate. The equipment is mounted on a 25-foot, 12-ton, tandem axle tagalong trailer that satisfies all Department of Transportation (DOT) requirements for day or night interstate highway travel at up to 65 mph without the need for any oversize permits. On graded dirt roads the trailers are capable of speeds of 25 mph. This allows for a great deal of flexibility in the utilization and positioning of the TFCUs on the Redstone Army Base or other military facilities, if needed.

Each TFCU includes a temperature control system that monitors and controls the temperature of the air in a large Test Chamber in a range from -65°F (+/-3°F) to 160°F (+/-3°F) using a single programmable controller located on the main control panel. The controller, a Yokogawa Model #UP550, stores a minimum of 4 user programmable profiles with 24-program steps minimum per profile.

The Conditioning Equipment Unit is mounted within a compact enclosure mounted on the trailer and is electrically powered by 460 VAC, 3 phase, and 60 Hz power. The refrigeration system is a cascade system that can pull down to -65°F in 12 to 24 hours from ambient using HFC refrigerants R-508B for the low stage and R-404A for the high stage. Suction, discharge Glycerin filled gauges, and oil pressure gauges that monitor the operation of the refrigeration system are mounted on the control panel.

The CEU is equipped with a fused, main power disconnect box protected by a NEMA 3R rainproof enclosure. Also provided is a 125-foot length reel mounted power cable terminated in a pigtail.
