Side-mount electrical cabinet air conditioner Model HT4840

verticalcompactfor computer rooms

Overview
Thermostat-controlled High Temperature Cabinet Cooler® Systems for ambient conditions from 125°F to 200°F (52°C to 93°C). These NEMA 4 (IP66) units incorporate low-pressure relief valves for both the vortex tube and cabinet exhaust; valves close when the cooler is not operating to preserve enclosure integrity. Standard thermostat control activates the cooler only when internal temperatures approach critical levels; factory set at 95°F (35°C) and adjustable. EXAIR Cabinet Coolers convert compressed air to cold air via a vortex tube with no moving parts and install through a standard electrical knockout. All units are UL Listed and CE compliant.

How It Works
Compressed air enters the vortex-tube powered Cabinet Cooler and separates into hot and cold streams. Hot air is exhausted to atmosphere; cold air is directed into the control cabinet via a cold air distribution kit. The cabinet is cooled and purged at slight positive pressure, preventing ingress of outside air while removing internal heat.

Accessories & Options

• Side Mount Kits: allow side mounting when top mount is not possible; maintain NEMA rating and fit a standard 1-1/2 NPS electrical knockout. NEMA 4/4X side mount kits are stainless steel.
• Cold Air Distribution Kit: tubing, clips and fittings to direct cold air to hotspots.
• Filtration: includes a 5 micron automatic drain water and dirt filter; coalescing (oil removal) filters recommended if inlet air contains oil.
• Control options: Standard thermostat control (factory set at 95°F / 35°C) or ETC (Electronic Temperature Control) upgrade for precise digital control and internal temperature feedback.
• Solenoid voltages: 120V 60Hz, 110V 50Hz, 240V 50/60Hz and 24VDC; solenoids are UL/CSA listed or recognized.

Specifications

• Ambient operating range: 125°F to 200°F (52°C to 93°C) for High Temperature models
• Thermostat: adjustable, factory set at 95°F (35°C); saves compressed air by operating only as needed
• Cooling capacity: 1,000 to 5,600 Btu/hr (293 to 1,641 Watts) at 100 PSIG (6.9 BAR)
• Typical cold air temperature drop: ≈54°F (30°C) below supply air at 100 PSIG
• Vortex tube cold stage: cold discharge up to ≈16°F (-9°C) below supply in vortex tube stage (depends on inlet)
• NEMA rating: NEMA 4 (IP66) — dust-tight, oil-tight, splash resistant, indoor/outdoor capable; includes low-pressure relief valves
• Construction: aluminum Cabinet Cooler with 303 stainless steel vortex tube; NEMA 4/4X side mount kits use stainless steel
• Filtration: 5 micron automatic drain water and dirt filter included; coalescing filter recommended when oil present
• Solenoid options: multiple voltages including 24VDC and 120/240VAC; UL/CSA listed/recognized
• Mounting: installs through standard 1-1/2 NPS electrical knockout; NEMA 4/4X units must be mounted vertically unless side mount kit used
• Maintenance: no moving parts — maintenance free; no room air filters to clog
