The flameless heater system includes an energy source comprising a diesel engine configured to create volumes of air, a hydraulic system to control engine loading for heat generation and for air moving, and a control system, operatively coupled with the energy source and the hydraulic system to control at least one of a speed of the diesel engine, a loading of the diesel engine, or a fan speed.

A portable heater shield assembly for directing heat laterally away from a heat source includes a plurality of panels that removably engaging each other to form a disk. Each of the panels is comprised of a heat resistant material. A plurality of brackets is each removably coupled to a heat source having the brackets being vertically oriented. The disk is positionable on top of the brackets when the brackets are removably coupled to the heat source having the disk spaced upwardly from the heat source. In this way the disk directs heat laterally away from the heat source for warming users sitting around the heat source.

An air handling unit (AHU) for a heating, ventilation, air conditioning, and refrigeration (HVACR) system includes a housing and a combustion heater disposed within the housing. The housing includes a combustion section with a first channel and a second channel. The combustion heater includes heat exchanger tubes and a tube support that supports heat exchanger tubes within the combustion section. The tube support slidably disposed in the first channel and the second channel. The combustion heater configured to be slidably removable from the AHU. An AHU for an HVACR system includes a housing with a fan section and a fan assembly disposed within the housing. The fan assembly including a pair of grooves slidably disposed on a pair of rails of the housing. The fan assembly configured to be both slidably removable from the AHU and liftably removable from the AHU.

A heating, ventilation, and air conditioning system includes a heating system. The heating system portion of the HVAC unit can comprise an array of heat exchanger tubes attached to a first side of a heat exchanger panel and a burner assembly attached to a second side of the heat exchanger panel. The burner assembly can comprise one or more tabs to facilitate installation and removal of the burner assembly within the HVAC system. The heat exchanger panel can comprise one or more slots that receive the one or more tabs of the burner assembly.

Disclosed is a high-temperature hot air blower capable of gathering energy and generating heat, including a machine housing (1) provided therein with a side wall (12) of a machine inner-side channel; an energy-gathering heat generator (13) is disposed on the side wall (12) of the machine housing inner-side channel and includes a heat generator transmission protective cover (14), a heat generator friction heat-generation body (15) and a heat generator heat-insulation isolation wall (16); the heat generator transmission protective cover (14) and the heat generator heat-insulation isolation wall (16) are respectively arranged on two sides of the heat generator friction heat-generation body (15), and are respectively in fit connection with the side surfaces of the heat generator friction heat-generation body (15); and the energy-gathering heat generator (13) is in fit connection with the side wall (12) of the machine housing inner-side channel via the heat generator heat-insulation isolation wall (16). The high-temperature hot air blower capable of gathering energy and generating heat disclosed herein can generate high-temperature hot air, and has the advantages of generating a large amount of hot air having a high hot air pressure, saving energy, having low noise, having multiple functions and a wide usage range, which can satisfy multiple usage demands for high-temperature hot air in production and living by people.

The disclosure relates to a coating system for coating components with a coating agent, in particular a painting system for painting motor vehicle bodywork components, comprising a first coating system component (12, 13) which during operation produces waste heat as a by-product and forms a heat source, and a second coating system component (1, 5) which is heated during operation and forms a heat sink. The disclosure provides that the waste heat of the first coating system component (12, 13) is fed to the second coating system component (1, 5) for heating. The disclosure further relates to a corresponding operating method.
