KUH Horizontal Unit Heater PDS

Product catalog summary

Overview: The KUH Horizontal Unit Heater is engineered for quiet and reliable fan-forced heating in commercial and industrial environments. It features Chromalox patented metal sheath Fintube® heating elements with steel fins for enhanced heat transfer and durability. These heaters are versatile, easy to install, and suitable for various heating applications, including primary, supplementary, and spot heating. They comply with UL and CSA safety standards.

Construction: The heater's cabinet is constructed from heavy 18-gauge steel with a corrosion-resistant finish. It operates quietly due to a combination fan guard and motor mount with rubber vibration isolators. The heating elements are designed for long-term, maintenance-free use. The units are available in power ratings from 2.6 kW to 45 kW and can be mounted on walls or ceilings.

Applications: The KUH heater is suitable for use in shipping rooms, pump houses, power stations, aircraft hangars, factories, warehouses, and garages. It can be used for primary, supplementary, dual system, spot heating, and as an air curtain for entryways.

Features: The heater includes a dynamically balanced fan for smooth operation, thermal overload cutouts for safety, and optional features like a disconnect switch, thermostat, and summer fan switch. It can be mounted using threaded rods or swivel brackets for adjustable airflow direction.

Electrical & Control Components: The heater includes heavy-duty magnetic control contactors, with optional contactors available for certain models. Models drawing over 48 amps have built-in fusing for protection. An internal 24-volt control transformer is standard on 480V models.

Specifications: Detailed specifications are provided for various models, including power ratings, voltage, phase, fan motor details, and mounting data. Application tips for optimal heater placement and usage in different environments are also included.

Mounting Recommendations: The heater should not be used in hazardous or corrosive atmospheres. It must be installed at recommended heights and clearances to ensure safety and efficiency.

Clearance Requirements: Specific clearance requirements are provided for safe installation, along with dimensions for different mounting configurations.

Mounting Limitations: The heaters must be mounted on smooth wood, plaster, or metal surfaces with adequate strength. They are not suitable for acoustic tile or suspended ceilings. The document specifies that the heaters should not be used in potentially explosive or corrosive atmospheres and should not be installed above the recommended maximum mounting height.

Installation Instructions: The heaters come with a swivel mounting bracket that allows rotation to the desired direction. Four bolts are provided for attaching the swivel bracket to the unit. Fasteners for mounting the bracket to the ceiling or wall are not supplied.

Optional Control Accessories: Various control accessories are available, including thermostat kits, fan-only operation kits, and power disconnect kits. Catalog numbers and product code numbers (PCN) are provided for ordering these accessories.

Thermostat and Fan Switch Options: Several thermostat and fan switch options are detailed, including internal and external summer fan switches and remote wall thermostats. Electrical ratings and catalog numbers for these components are provided.

Ordering Information: When ordering KUH heaters, customers should specify the model number, PCN, voltage, phase, and kW. A detailed breakdown of model numbers and corresponding options for disconnect switches, controls, and heating elements is provided.

For individual spaces total heatingcapacity is calculated in the con-ventional way, using formulas in theASHRAE GuideӔ or those found inthe NEMA handbook. > For pedestrian entryways whenheating capacity is not known, a rule of thumbӔ is 3000-5000 wattsper door. Use 3000 watts per doorfor a low traffic single-door entry. For a large multiple-door entry, or ahigh traffic single-door entry, use5000 watts per door. > Loading Docks .
