Planetary gearheads suit harsh washdown environments

09 May 2011

Heason Technology has added a new range of all stainless-steel, washdown grade planetary gearheads from its manufacturing partner Thomson

The new AquaTRUE range is aimed at high precision positioning in wet cell processing applications for food and beverage, chemical and pharmaceutical production, caustic cleaning and other harsh environment areas where frequent high pressure spray or corrosive environments would seriously reduce the life of standard grade gearboxes.

The low-backlash gearboxes have a precision of 13 arc-min with four nominal frame diameters from 60 mm to 160 mm, output torque to 875 Nm, and ratios from 3:1 to 10:1.

With high radial and axial load capacity and efficiency to 93%, the AquaTRUE design includes silicone gasket sealing and is supplied with IP66/67 or optional IP69K for total protection against close-range high pressure spray. The 304 grade stainless housings have no external seams or corners that can harbour dirt of bacteria and such protection eliminates the need to provide additional enclosures to isolate the gearhead in harsh environment applications.

Heason Technology also supplies a range of washdown and food grade servomotors from its distributor partner Kollmorgen, a sister company to Thomson. Part of the acclaimed Kollmorgen AKM range, these precision servomotors include IP67 sealing with a highly effective 2K polyurethane external coating for maximum protection against alkaline and acid solutions in addition to stainless steel hardware on all precision surfaces.

Washdown and food grade versions are available in motor frame sizes two through six with output torques up to 25 Nm and are a cost effective solution for motion control in food and beverage production, packaging machinery and many other applications where washdown is essential.

The AKM range has BISSC certification (the USA Bakery Industry Standards Committee), and is available in 90 VDC and 180 VDC in ¼ and ½ HP ratings and speed to 1750 RPM.

Heason Technology is a Premier Partner programme member with Thomson and offers complete sales, technical support and service across its range of linear bearings and power transmission equipment.

Heason also represents Kollmorgen along with a number other leading motion control equipment manufacturers and through its own in house design and assembly service provides customised electro-mechanical positioning system solutions for challenging applications across, aerospace, automotive, defence, robotics, process control, packaging, motorsports and many more.
