Info & Guides

Description

An ordinary room air conditioner can be a hazard in a space with flammable vapors or liquids. The Friedrich Hazardgard 21,000 BTU Window AC (model SH20M50B) deals with that through sealed construction. The fan motor and the rest of the key components stay housed inside the cabinet, away from the hazardous air you need to cool.

You can fit it to the building you have. Mount this Hazardgard in a single- or double-hung window, or install it through the wall, and use the installation kit that comes in the box. The steel construction and coated coils are built to resist corrosion, which matters at industrial sites.

Key Features and Benefits of the Friedrich Hazardgard 21,000 BTU Window AC

  • T4 Temperature Class: A Temperature Class T4 rating and a maximum surface temperature of 275 degrees F let you run it safely around flammable liquids and materials.
  • Cooling Capacity: Provides 21,000 BTU of cooling at a maximum draw of 11.6 amps and 6,150 watts, enough to cool large industrial rooms.
  • Wide Operating Range: Cools in ambient temperatures from 45 to 130 degrees F without freezing up, so it keeps working through hot summers and cool shoulder seasons.
  • Airflow Volume: Moves up to 425 CFM of air on its single fan speed, so cooled air reaches the far side of larger work areas.
  • Corrosion-Resistant Build: Anti-corrosion coated coils plus a steel cabinet and fan shaft hold up in the corrosive air of refineries and offshore platforms.
  • Moisture Removal: Pulls 7.0 pints of moisture from the air every hour through a condensate drain, helping keep damp work areas drier and comfortable.
  • Efficient Operation: A split capacitor motor limits energy use at startup, and an 8.8 Energy Efficiency Ratio helps you keep operating costs under control.
  • Refrigerant Type: Uses R-410A, so your HVAC technician knows exactly which refrigerant to use during service.
  • Hardwired Power: Hardwires into the included junction box on 208/230-volt, 50-hertz power with a 250-volt, 15-amp breaker, so your electrician can plan the circuit ahead.
  • Manual Controls: A toggle power switch and rotary temperature knob let anyone on shift adjust cooling quickly, with no menus or programming.
  • Washable Filter: A permanent washable air filter traps allergens and airborne impurities, and the front clips release quickly when it needs rinsing.
  • UL Listed: UL certification confirms it was independently tested for safe operation, which gives your safety team documented verification.

Window or Wall: Check Your Opening Before Installation Day

For a window installation, your opening needs to be 27.875 to 42 inches wide and at least 18 inches tall, in a single- or double-hung sash. The cabinet measures 27.375 x 25.93 x 17.93-Inches (L x W x H) and weighs 171 pounds, so plan support and lifting before installation day.

Sylvane's Expert Take

If you run a refinery or an offshore platform, this is the window air conditioner to specify when flammable materials rule out a standard room model. It works best in large, enclosed spaces like control rooms and labs that are staffed all shift.

There is no plug, so book an electrician for the hardwired connection. The T4 rating and corrosion-resistant coils matter most, and together they make this a Friedrich cooler you can install once and trust in a harsh environment.
