LHS 91
As the most powerful Leister industrial heater, the LHS 91 is designed for the most demanding heating applications—so powerful it can replace many gas-fired heaters.
The LHS 91 is capable of reaching temperatures as high as 1202 °F, and effectively heats airflows up to 320 cfm.
This industrial heater is available in two versions to satisfy your control needs:
- Basic—One-level heating power, which can be controlled only through an external air source.
- System—Heating power can be controlled via a remote control interface for integration into open- or closed-loop systems, and includes potentiometer dials for manual control, and an alarm output for heating-element and device overheat protection.
