The Tradition Continues...
The New Maxx 450, 450D and 470

The Hydramster Tradition of leading the industry in the development of new carpet cleaning equipment and technology continues with the new Maxx 450, 450D and Maxx 470. These new units offer incredible performance features while maintaining Hydramaster's reputation of building rugged reliable systems that are easy-to-use and simple-to-maintain.

Daihatsu Industrial Engines power both the Maxx units. Built by Toyota, these cast iron, water cooled motors have a worldwide reputation of long lasting, dependable service. The Maxx 450 uses a 3-cylinder 23.5 horsepower motor to turn a Tuthill 4005X blower, while the 470 uses a 31-horse engine coupled to a Tuthill 4007X blower. Both motors have a 3 speed electronic governor for ease of operation and improved fuel economy.

Maxx Heat Systems Technology sets a new standard for performance and reliability. Operating temperatures up to 250°F are generated by a multi-stage system. The system captures heat from the blower and engine exhaust and the engine cooling system. Unlike units that control heat by dumping water into the waste tank, the Maxx series has ADC, a Hydramaster exclusive that electronically controls the amount of exhaust gases sent through the catalytic converter heat exchanger. The result is a very high volume/high temperature system that doesn't waste recovery tank capacity. The Hydramaster designed, cast stainless steel diverter valve at the heart of the system is built heavy duty for dependable long-life operation.

An extra large 100 gallon recovery tank is standard on the Maxx. Constructed of marine grade aluminum, the tank features a reversible lid (for side or back door installation), a new high efficiency vacuum relief valve, and a stainless steel lint basket. The basket is easy to remove and clean making daily maintenance less of a chore. An optional, externally mounted, high capacity belt driven pump-out system is available.

New Maxx Technology!
ADC Diverter Heat Control System
The Maxx Performance Series uses an exclusive new heat system technology that controls temperature without dumping hot water into the waste tank. Coupling a thermostat to an actuator, temperature is controlled by opening and closing the stainless steel diverter valve. Solution temperature can be varied between 160°F to 250°F or turned off for flood restoration.

New Patented Chemical Pulse Pump
Designed by Hydramaster Engineers, this long life pump will still be working after others have failed. This Last-Step Chemical System is equipped with a special heavy-duty diaphragm. The pump is built to withstand high pressures and high temperatures and still operate smoothly. When it does need service, the robust 3 piece pump housing is easy to dissemble and repair.

Race Car Components on Your Truckmount
No one wants to stop in the middle of a job and fix a broken or loose belt. That's why Hydramaster uses a Poly-Chain & Sprocket Drive to connect the motor to the blower, just like those found on high performance race engines. Poly-Chain Belts have an extraordinary long life and never slip and lose power like standard belts.

Quality Designed and Built Throughout
Closely examine the Maxx System and you will see the attention to small detail also sets it apart from other units. Where other units have plain steel fittings or plastic, you'll find quality brass and stainless steel connectors and components.
