Hi Delta outdoor boiler 270-640 kWThe Hi-Delta 992ACE-2342ACE series gas appliances can be used as heating boilers of central heating systems with liquid medium.
As a boiler they can be installed: indoor (in a conventional boiler room),
outdoor (without any structure around them)
As a water heater they can be installed:
indoor (in a conventional boiler room),
outdoor (without any structure around them), if there is no risk of freezing.
As a water heater for direct heating of:
domestic hot water
hot water for technological purposes
swimming pools
The combustion air is being drawn by two or three blowers direct from the adjacent area of the gas appliance or through air intake pipes. The flue gases can be discharged through small diameter horizontal or vertical vent systems which are typical for gas appliances operating under positive pressure. Outdoor installations are self-venting when installed with the optional factory supplied outdoor vent kit and do not require additional vent piping. The gas is burnt in 100% primer air premix stainless steel burner tubes enclosed with the heavily heat insulated combustion chamber. Low emission is thanks to his feature. The heat generated in the low mass and low volume die-rolled copper fin tubes which are resistible to 12 bars can be removed by the intensive flow of the heat transfer liquid.
Typical areas of applications:
High temperature heating systems with 96% thermal efficiency
Direct heating of domestic hot water or swimming pool water with 94% thermal efficiency
Technological processes, up to 105 Celsius flow temperature
Versatility and references
They can operate reliably in the most extreme operating conditions. Solutions for a variety of unusual tasks:
Valuable building areas are released
Otherwise insignificant areas are utilized
No boiler room is needed
Eliminates the cost of chimney construction.
A wide range of flue systems or the option of outdoor installation might make possible the use of gas appliances can be considered at all, and thus the total cost of the construction might be greatly reduced.
Numerous achieved installations demonstrate their worthiness.
Scope of delivery, accessories
The Hi Delta units are supplied full assembled according to the ordered specification.
Small weight and dimensions make the shipment to the application site easy. Easy disassembly and assembly, if necessary, the parts can be supplied to the site manually without difficulties.
Two Hi-Delta units can be installed over each other.
High-strength, heat-shock resistant heat exchanger
The heat exchanger is suitable for direct contact with drinking water. The finned tubes are manufactured of a single, thick-walled plain copper pipe starting to be rolled and crimped along helically thus resulting large heat transfer finned tubes made of its same solid material.
Ultra-lightweight, durable design, silent operation
The load of the floor does not exceed 325 kg/m2.
The outer cabinet is completely closed: corrosion-resistant, galvanized-coated sheet steel, powder-coated in plastic.
Silent operation makes any further protection against noise or vibration unnecessary.
Exchangeable connection terminals: flue gas, air, water, gas, electricity
Low emission main burners
The 100% Fan assisted 100% premix burner tubes are made of titanium-chromium stainless steel alloy resulting low NOx emissions. Less than 30 mg / kWh, on natural gas.
Central control diagnostic unit
Hot surface ignition system and flame ionization.
Dual ignition. Two separate and independently operable ignition system for larger appliances.
Intermittent primary circuit pump control with adjustable pump overrun to reduce standby heat losses and electric consumption.
They have single- or multistage burner control to be connected to various analogue or digital controllers ranging from a single constant temperature thermostat through weather-compensated digital controllers of a heating system up to a complex network of integrated building management systems.
Operating status / error conditions displayed on-site, remote control or transmission of the error signal on request.
Installation methods
Outdoors, without flue pipe system
Outdoors, connected to flue pipes
Inside a boiler room, vertical vent system, open or closed combustion chamber
Inside a boiler room, horizontal vent system, open or closed combustion chamber
