UL Series Skid-Mounted Environmental Control Units

Key Features

  • 16ga Aluminum (Cabinet) & 14ga Steel (Skid Base)
  • High-Efficiency, Tube-and-Fin Evaporator Coil
  • High-Efficiency Micro-channel Condenser Coil
  • Motorized, High-Efficiency Reversed-Inclined Evaporator Blower
  • Motorized, High-Efficiency Condenser Axial Fan
  • Variable-Speed Controller for Evaporator Blower (4-ton Only)
  • Best-in-Class Copeland® Scroll Compressor
  • Environment-Friendly Refrigerant R-134a
  • Electronically Controlled Valves
  • Remote Control Box w/ Electronic Temperature Controls (Cooling & Heating)
  • 20-ft (Standard Length) Remote Control Cable
  • Mil. Circular Power and Control Connectors
  • Designed for High Ambient Operation in Outdoor Conditions of up to 150°F
  • Externally Accessible Sight Glass and Servicing Ports
  • Permanent Washable Air Filters
  • Stainless Steel Drain Pan
  • Skid Base with Corner Quick Receivers for Inserting Wheels, Leveling Stands or Lifting Rings
  • Durable Powder Coat Finish

Upgrades Available

  • HEPA Filtration – Captures 99.97% of 0.3-micron particles
  • UVC Light Sanitization – Kills 99.9999% of bacteria, viruses and air-borne pathogens
  • Insulated Ducting – PVC/Polyester material; Three-Ply, Insulated Ducting; mold and mildew inhibitors for rigorous outdoor use
  • Mil-Spec – Built for MIL-STD 810F Compliance – resists vibration during transportation and harsh environments (sand/dust, dripping rain, salt fog)
  • Humidity Control (Electric Reheat) – Reheats the supply air to lower the relative humidity (%RH) of the air entering the controlled space, thus drying the space out to the desired humidity level
  • Low Ambient Controls – Operates in colder environments (of below 50°F)
  • Constant Run – Allows precise load matching cooling (through electronic hot gas bypass); Extends life of the Compressor – eliminates transients that result from compressor cycling
  • Electric Heat – resistive single-stage, for heating in all environments and conditions
  • Humidity Control (Immersed Electrode Humidifier) – With integrated conductivity sensor and control software (to optimize energy efficiency and maintenance costs), produces steam, raising the %RH to the desired humidity level

Typical Applications

  • Telecommunication (Satellite Antenna Hubs)
  • Military Shelters (Command & Control)
  • Medical Shelters
  • Portable Buildings
  • Temporary Barracks (Sleeping Quarters)
  • Medical Tents
  • Dining Facilities/Mess Halls
  • Operating Bases
  • Tactical Operations Centers
  • Humanitarian Emergencies
  • Collective Protection (ColPro) Tents (NBC Filtered air)
