Heating and Cooling in One Portable Unit
Unlike traditional cooling-only spot coolers, the ClimaTemp CPTH-18EX provides both heating and cooling through its portable heat pump system.
This allows commercial facilities to use one piece of equipment for changing seasonal conditions and temporary temperature-control needs.
Cooling Mode — 15,000 BTU/hr
In cooling mode, the CPTH-18EX removes heat from the conditioned area and supplies cooled air toward the intended space.
Its 15,000 BTU/hr cooling capacity is useful for appropriately sized offices, workstations, equipment rooms, and temporary HVAC applications.
The manufacturer’s specification sheet lists a 64°F–113°F cooling operating range.
Potential applications include:
- Commercial offices and retail spaces
- Manufacturing workstations
- Network closets and equipment rooms
- Supplemental air conditioning
- Temporary cooling during HVAC maintenance
- Emergency commercial cooling
Because the CPTH-18EX is an air-cooled heat pump, the installation must provide suitable airflow and a means to reject condenser heat away from the cooled space.
Heating Mode — 13,600 BTU/hr
In heating mode, the CPTH-18EX transfers heat to the intended conditioned area.
Its 13,600 BTU/hr heating capacity makes it suitable for supplemental heating in appropriate commercial and industrial spaces.
The manufacturer’s specification sheet lists a 39°F–80°F heating operating range.
Common heating applications include:
- Offices and commercial buildings
- Workshops and maintenance areas
- Temporary workspaces
- Warehouse workstations
- Commercial renovations
- Supplemental heating during HVAC maintenance
Heating performance depends on ambient conditions, airflow, and proper heat pump installation.
Common Applications for the CPTH-18EX
Commercial Offices and Retail Buildings
The ClimaTemp CPTH-18EX is useful for commercial spaces needing supplemental heating in cooler weather and localized cooling during warm conditions.
Its portable cabinet allows the equipment to be repositioned between suitable areas without installing a separate permanent heating and cooling system.
Warehouses and Manufacturing Facilities
Industrial workstations and production areas may require localized temperature control.
The CPTH-18EX can provide supplemental heating or cooling for appropriately sized work areas, maintenance rooms, packaging operations, and workshops.
Its locking casters, protective bump guards, and removable filters make it practical for commercial facilities where equipment is moved frequently.
Server Rooms and Equipment Cooling
The CPTH-18EX can provide temporary or supplemental cooling for properly sized server rooms, network closets, and telecommunications equipment spaces.
Proper condenser heat rejection, compatible electrical service, condensate management, and cooling-load calculations must be considered.

Temporary HVAC and Emergency Applications
The ClimaTemp CPTH-18EX is suited for temporary heating and cooling applications such as:
- Emergency HVAC replacement
- Commercial building renovations
- Temporary office spaces
- Supplemental heating
- Seasonal spot cooling
- Industrial maintenance projects
- Commercial equipment rentals

Electrical Requirements
The ClimaTemp CPTH-18EX operates on 115V single-phase electrical power.
Unlike smaller portable heat pumps that may operate on a standard 15-amp circuit, the CPTH-18EX requires a compatible 20-amp electrical circuit and NEMA 5-20 receptacle.
Published electrical specifications include:
- Power Supply: 115V Single Phase
- Current Consumption: 14.3 Amps
- Fuse Size: 20 Amps
- Plug: NEMA 5-20
- Voltage Range: 105–125V
- Power Cord Length: 6.6 Feet
The NEMA 5-20 plug requires a compatible T-slot receptacle.
Do not connect the unit to an undersized electrical circuit or use an adapter to bypass the required receptacle configuration.
Always verify the electrical requirements on the actual equipment nameplate before installation.
Condensate Management
The CPTH-18EX includes a 6-gallon condensate collection tank.
The tank collects moisture generated during applicable operating conditions.
When the collection tank reaches its limit, the unit activates its automatic full-tank protection and audible alarm.
For installations where frequent manual emptying is inconvenient, ClimaTemp offers an optional Beckett-brand plug-and-play condensate pump.
The condensate pump is an optional accessory and is not included as standard unless specifically listed in the equipment quote.
Portable Heat Pump Airflow and Installation
The CPTH-18EX uses an air-cooled heat pump system.
Proper airflow management is important in both heating and cooling modes.
Cooling Installation
In cooling mode, the unit removes heat from the conditioned space.
Hot condenser air must be directed away from the cooled area so the equipment does not simply reintroduce the rejected heat.
Heating Installation
In heating mode, the heat pump transfers heat from its source air to the heated area.
The intake and discharge arrangements must follow the manufacturer’s installation instructions so the unit has adequate heat-exchange airflow.
Before ordering accessories, confirm the correct condenser duct connection, allowable duct length, and heating/cooling airflow requirements for the CPTH-18EX.
Designed for Commercial and Rental Applications
ClimaTemp includes several features intended to simplify operation, transportation, and maintenance.
QuickMove Removable Filters
The evaporator and condenser filters can be removed for cleaning and inspection.
This simplifies routine maintenance between commercial deployments.
Heavy-Duty Locking Casters
Locking casters allow operators to reposition the unit and secure it on appropriate indoor surfaces.
Protective Cabinet Construction
Side bump guards help protect the cabinet during transportation and frequent handling.
The attachable rear kick plate assists with movement across door thresholds.
Digital Controls and Automatic Restart
The LED controller supports operating-mode selection, temperature adjustments, and diagnostic troubleshooting.
The automatic restart feature helps restore operation following certain power interruptions.
Optional Accessories
Beckett Plug-and-Play Condensate Pump
The optional Beckett condensate pump can provide automatic moisture removal for compatible installations.
Contact Climate Control Solutions to confirm pump compatibility, pricing, and availability.
Heating and Cooling Ducting
The CPTH-18EX may require compatible air routing or ducting depending on the installation and operating mode.
Confirm the manufacturer-approved connection dimensions and allowable duct lengths before selecting accessories.
