Triggerless gun cuts operator fatigue
December 1st 2004

The new Hammelmann Ergoblast 3000 high-pressure blast gun being launched by Calder represents a major design breakthrough. It has done away with the conventional trigger, making life less tiring for the operator and provides unrestricted pressurised water flow resulting in better cleaning performance

To operate the new advanced, futuristic gun the operator wears a small transponder on his finger. As the hand is moved onto the grip-handle a signal is received by a piezo switch within the gun, this in-turn generates a signal via a single wire to the controls of the high-pressure pumping machine to initiate water flow. When the hand is removed from the grip-handle water flow stops.

The grip-handle with its integral receptive sensor covers virtually the full length of the lance allowing the hand to move freely for optimal, comfortable working allowing maximum cleaning. The design gives total flexible directional working, making muscle cramp a problem of the past whilst also eliminating the fight against the reaction force and the complaint of dead-hand.

What Ergoblast 3000 brings to the market is a high-pressure water jetting system that is a remarkable design that not only improves ergonomics for the user, it also allows more effective real-time cleaning. Its a combination that should make a major impression within the industry.

The triggerless Ergoblast 3000 development brings great operational benefits. Elimination of trigger means no valve and there are no sharp bends in the water path, its a combination that dramatically reduces pressure loss and eliminates turbulence which means the full force of the water jet is available to do its job.

Ergoblast is a design where maintenance has seen its day no moving parts, no mechanical wear and no seals or orifice housings. A wide range of applications is made

possible by a full range of nozzles and

lance extensions also available from

Calder.
