Description

Reznor's LDAP Series Packaged Downflow Heaters are perfect for large high bay warehouses and factories. The downflow configuration with the Destratification mode allows the unit to send hot air around the roof to the floor.

The LDAP units have four suspension points for hanging or wall mounted capability. All Model LDAP heaters are certified for 83% thermal efficiency for use with either natural or propane gas and are available in three sizes - 400 MBH, 800 MBH, and 1200 MBH.

Each heat section features the Reznor® TCORE2® heat exchanger and single burner combustion system. Operation is controlled through an integrated circuit board using LED diagnostic indicator lights to identify abnormalities in control functions.  Designed for ease of installation with an external 24-volt terminal strip and gas line connection.

Model LDAP heaters are tested to ANSI and CSA standards by the ETL Testing Agency for commercial and industrial applications.
