STJH-FLANGED-DUCT-ELECTRIC-HEATER-20KW

Flanged Duct Electric Heater 20 kW Eight-Inch

A 20 kW eight-inch flanged duct heater using 24 finned elements at a low 3 W/in2 surface loading.

20 kW heating capacity
24 finned elements
3 W/in2 low watt density

Introdução do produto

This final-stage heater spreads 20 kW across 24 finned elements on an eight-inch flange. The low 3 W/in2 loading moderates element surface temperature for sensitive clean process air and downstream temperature trim.

Características-chave

Gentle final-stage heating

Low surface loading supports controlled air-temperature trim without concentrating heat on a few elements.

Dense element distribution

Twenty-four elements spread output across the flow path for more even heat input.

Eight-inch flanged service

The assembly bolts into a matching duct or circulation-heater housing as a removable stage.

Applications

Sensitive clean process-air trim, final duct heating, controlled drying air and low-surface-temperature air systems.

Solutions for Your Application

High element surface temperature could overheat sensitive process air or deposits.Use the 3 W/in2 loading and interlock heat to proven airflow.

Uneven heat across the duct creates hot and cold zones downstream.Distribute the 24 elements across the active flow area and provide adequate mixing distance.

Opções disponíveis

Sheath alloy, supply voltage, power stages, SCR control, airflow switch, high-limit sensors and terminal enclosure can be selected.
