RF MacDonald Co. has been a representative for AJAX since 1959!
AJAX
boilers perform dependably and quietly, providing commercial, institutional,
and industrial buildings with space heating, domestic, and process hot
water.
Inclined tubes provide uniform heat transfer, resulting in high fuel economy and long boiler life. 2" OD tubes (steel or copper) are rolled into large headers on both ends, producing excellent boiler circulation. 2" OD tubes are less restrictive than smaller OD tubes.
Our non-proprietary tubes are less costly for tube replacement. Ajax's straight tube design allows for individual inspection of tube conditions.
AJAX Boilers feature:
- Inclined Water Tubes with large headers for excellent internal circulation
- Models from 150,000 BTU/Hr to 21,000,000 BTU/Hr fit every application
- Effective Heat Transfer Surfaces triangular pitch-multi-row heat exchanger
- High combustion efficiency radiant refractory combustion chamber
- 85% High Efficiency Boilers
- Low NOx Boilers
- High Pressure Steam Boilers from 5 to 350 BHP
- Thermal Shock Proof floating tube bundle and headers
Full 20 years non-prorated Thermal Shock warranty on all boilers
Constructed
and Stamped to ASME BPV Code Section IV, is supported by a rugged steel
frame with expansion joints at each corner. This simple but effective design
allows the entire tube bundle to float freely as it expands and contracts
during normal operation. Free floating tube bundle prevents thermal shock
damage. (Boiler tubes are rolled into headers.) The key to preventing waterside
corrosion in any boiler is to eliminate air bubbles. This is accomplished
by sloping the tubes upward 1/2" per linear foot from the rear to the front.
This enables the boiler water to carry the air bubbles to the built-in air
eliminator. No air bubbles means no pitting or corrosions.
Ajax Series "H" & "X" Tube Bundle and Drum Assembly
The
Ajax Series "H" & "X" boiler is an adaptation of Ajax basic Series
"W" design providing drum construction for large steam or water storage
capacity.
Constructed and Stamped to ASME BPV Code Section IV.
Ajax Atmospheric Burner Assembly
Multiple
numbers of burner heads make up the Burner Assembly, each with its own venturi
and orifice. The drilled, raised port, grey cast-iron burner head has long
been recognized as the simplest, most trouble free gas burner available.
There is nothing to get out of adjustment; therefore there is nothing to
adjust.
Ajax Heat Exchanger
Ajax
Indirect Heat Exchangers are constructed with copper tubes, bronze headers
and tube sheets. They are available in sizes up to full capacity of the
boiler and easily adaptable for domestic water heating for laundry, dishwashing,
shower, swimming pool, and snow melting applications. Water to water or
steam to water heat transfer for maximum efficiency.
Also available with ACE double-wall tube bundles
Ajax Series "S" Tube Bundle and Drum Assembly
5-70
HP. This boiler utilizes cylindrical headers and steam drum. Sloping tubes
promote water circulation and proper steam flow. Boiler tubes are straight
inclined with bolted and removable head plate covers which allow visual
inspection and mechanical cleaning of tubes.
Series "S" boiler for 150 psi steam. "D" series boiler (not shown) is similar in design, for water and high temperature hot water.
Constructed and stamped to ASME BPV Code Section I.
Ajax Series "S" Tube Bundle and Drum Assembly
80-350
HP. In this design the steam drum is mounted between cylindrical headers
to minimize overall height.
Series "S" boiler shown for 150 psi steam. Series "D" boiler (not shown) is similar in design for water and high temperature hot water for 80-350 HP.
Constructed and stamped to ASME BPV Code Section I.
