Performance:

• Robust construction, designed to operate 24/7 in temperatures down to -60 °F

• Highest heat rise of any heater up to 240 °F

• 3,000 hour oil service intervals and extended run time with its 256 gallon tank, for maximum uptime on the jobsite

• Durable heat exchanger made from 100% 309 stainless steel comes standard with 5 year warranty

• Unique Recircul-Air™ design allows adjustable recirculation of warm inside air, resulting in huge fuel savings and even temperatures

• Machine longevity vs. flameless for lowest total cost of ownership

Safety:

Combustible Gas Detection System with Positive Air Shutdown:

• Continuously samples the air for methane, preventing startup until air is gas-free

• Disables the burner at 10% of the explosive level of methane

• Engages a positive air shutdown at 20% of the explosive level, safely shutting down the entire machine

• Restart interlock ensures no live components until air is methane free

• Is 3rd party tested under real-world conditions, with live methane release

• Triple threat spill containment feature ensures that no diesel fuel, engine oil or engine coolant will contaminate the site

The HI 770XHD Indirect-fired air heaterThe performance you need with the safety you requireDesigned and built for extreme environments, the HI 770XHD is now available with an optional gas detection system for potentially volatile applications such as Oil and Gas Exploration. Don’t choose between performance or safety, instead choose the HI 770XHD from Wacker Neuson.

Selecting the right heater

Indirect fired vs. flameless heat

We understand safety is priority one on any jobsite, especially when it involves potentially volatile conditions. We also understand the need to maximize up-time and optimize efficiency for the best return on investment. That’s why Wacker Neuson has developed multiple solutions to match our customers’ heat requirements, while creating ideal work environments.

• When high heat rise and minimal service intervals are essential choose the HI 770XHD W/Gas Detection System

• When “Flameless” is a mandatory requirement choose the HIF 690 or HIF 1200 Flameless Air Heaters

Both machines are designed to work in potentially hazardous environments and both are CSA certified.
