Category: Cartridge Housings
Series: HT

## Overview
HT is a multi-cartridge housing for high-temperature process fluids such as heat transfer oils. The ANSI blind flange cover uses through-bolts, while extended inlet and outlet nozzles leave room for protective insulation. The vessel’s pressure class, gasket and filter element must be selected together for the required temperature.

## Key Features
- ANSI blind flange flat-top cover with through-bolt closure.
- Inlet and outlet nozzles are extended by 6 inches to accommodate insulation.
- Mechanical davit on HT10 and larger; handled cover on smaller models.
- DOE cartridges or 1-inch NPT single open end configurations can be specified.

## Applications
- Air & Gas
- Chemical
- Pulp & Paper
- Electronics
- Coatings
- Oil & Gas
- Coolant
- Power
- Marine
- Equipment
