KNHX32 - Integrity Series KNHX32 NEMA 4/4X
- Brand: Kooltronic
- Product Code: KNHX32
Description:
Description
KOOLTRONIC Integrity NEMA 4/4X Heat Exchangers are intended
to complement the Integrity NEMA 4/4X
Air Conditioner product line for those applications that require
the protection of closed-loop cooling, but can tolerate operating temperatures somewhat
above the ambient.
Tested and rated by Underwriters Laboratories, these uniquely designed (Patented)
stainless steel heat exchangers provide a clean, cool internal environment and also
protect against the hazards specified for both Indoor and Outdoor
NEMA 4 and 4X Enclosures.
These units can be mounted interchangeably with KOOLTRONIC
Integrity NEMA 4/4X Air Conditioners for maximum flexibility
in selection, upgrading or reducing cooling performance, if requirements change.
The outer cover mounting holes as well as the cool air discharge and heated air
return cutouts are identical (except cool air discharge of 32 model), so that
either type of cooling unit could be used.
More powerful ambient-side blowers are used than in comparably sized standard
KXHE and
KXNP models, to overcome the added static
pressure caused by the special baffles and dampers required to comply with NEMA
4/4X sealing and performance standards.
For extreme ambient temperatures and/or severely contaminated environments, the
use of Water-to-Air Heat Exchangers
or either Air-Cooled or
Water-Cooled Air Conditioners is recommended.
KOOLTRONIC also designs and manufactures a variety of heat exchangers to meet
unique specifications. We invite your inquiries about our modification and
custom-design capabilities.

Data
Epoxy-coated convoluted aluminum element
- Fabricated to the same standards as the uncoated convoluted aluminum elements, these are made from epoxy-coated aluminum stock that exceeds 1000 hour salt spray testing requirements.
Filter
- All KOOLTRONIC filters consist of a multi-layer grid of sturdy corrugated aluminum, securely held in a one-piece aluminum frame. Filters are required wherever air is drawn into an electronics enclosure or related cooling equipment to keep internal parts as clean as possible. A non-drying adhesive coating traps a high percentage of particulate matter. These filters are reuseable, they may be washed and recoated with the appropriate filter recoating adhesive. Replacements are available for those which become damaged or otherwise non-serviceable.
NEMA 4/4X Rating Maintained (UL50)
- All units are fully gasketed for tight, leakproof installation, in compliance with the NEMA 4 and 4X Enclosure Ratings.
Stainless Steel Shell
- For applications in corrosive or other hostile environments such as those requiring Internal Corrosion Resistant Coatings, especially where chemical/moisture combinations are present.
Filter Recoating Adhesive
- This compound is a superior product for recoating filters after washing. The adhesives penetrate dirt layers to keep the filter surface tacky for longer effective performance between washings.
Lifting Eyes
- Heavy-gauge steel lifting eyes, attached to the side panels, assist in positioning units.
Low Airflow Detector
- Similar to the Airflow Switch shown in the Blower Accessories Section, the switch is installed in a suitable location in the air conditioner to detect loss of airflow, and sends a signal to a terminal block, through which user-installed wiring and warning devices are activated.
Replacement Filters
- All KOOLTRONIC filters consist of a multi-layer grid of sturdy corrugated aluminum, securely held in a one-piece aluminum frame. Filters are required wherever air is drawn into an electronics enclosure or related cooling equipment to keep internal parts as clean as possible.,A non-drying adhesive coating traps a high percentage of particulate matter. These filters are reuseable, they may be washed and recoated with the appropriate filter recoating adhesive. Replacements are available for those which become damaged or otherwise non-serviceable.
Temperature Alarm
- A thermostat is mounted inside the cabinet and attached to a sensor in the warm air return. When the air temperature increases to the set point, a signal is sent to a terminal block. User-installed wiring from the terminal block to local and/or remote warning devices (light, bell, siren, etc.) can be for normally open or closed operation.
