CLEAN IN PLACE

No need to brush or bag, just wash it away.

service 1

Beats Corrosion

All external components including motor shafts are manufactured in 304 series stainless steel. This gives excellent corrosion resistance. With a highly chemical resistant surface (no paint to flake off) they far out-live standard painted motors in hygiene applications.

service 2

Washdown Tolerant

EUROPEAN manufactured and exceeding IP66 during external testing, the Marlin Stainless range is a proven design for CIP (Clean in Place) areas and washroom situations. A Viton double lip seal and a second GAMMA seal fitted on the shaft are examples of the attention to detail for protection against potential ingress during wash down.

service 3

Where Hygiene Counts

Unlike standard motors the Marlin Stainless range has "clean lines" and no cooling fins. Designed with cleaning in mind, it has no paint to chip or flake off, no surface that will rust. Waste products can be washed away easily leaving no residue and the motor can be used with confidence in food processing areas. Even the rating plate is laser etched on the outer casing to reduce areas where bacteria can lurk.

CLEAN FEATURES

project 1

Rated for...

"STATIC" FREQUENCY CONTROLLERS/VARIABLE SPEED DRIVE OR INVERTER USE
The whole Marlin range is suitable for inverter drive use and has phase barriers and PTC thermistors fitted as standard. On request PTO (Klixon style) bi-metallic thermostats can be fitted as an alternative to protect against over-temperature.
project 2

Etched Nameplates

The nameplates and fixings on standard motors are prime areas for waste and dirt entrapment.
They corrode, get damaged and even detach. The Marlin Range has the technical data etched directly onto the motor body, thus eliminating these hygiene and safety risks.
project 3

IP66 Sealing

Defined by IEC 34-5 and BS 4999 pt 105, the code consists of 'IP' Ingress Protection rating: two digits, the higher the numbers, the higher the protection.
The first digit relates to the ingress of dust or solid particles, but it is the second digit which is of paramount importance for this product range, as it relates to the protection level against water projected in powerful jets from any direction. This makes the product ideal for critical washdown applications.
project 7

TEFC and TENV

Totally Enclosed Fan Cooled motors rely on air being pulled from the non-drive end of the motor through a fan; this is then blown over the motor body to help dissipate the generated heat.
Totally Enclosed Non-Ventilated motors work on the basis of more active material and optimised efficiencies, reducing the heat generated through losses thus negating the need for a fan.
The TENV types are standard up to and including 0.75Kw and due to their design, have cleaner lines and fewer areas for entrapment of dirt or waste product.
project 8

Tropicalised Internal Components

Corrosion-resistant rotors and advanced winding varnishing techniques dramatically increase the motor's reliability and expected lifetime.
project 9

Round Terminal Box as Standard

The round smooth terminal box, which is machined and welded directly onto the frame of the motor, has fewer places to trap water or dirt.
It also benefits from smooth hygienic gland-seat extension, proving again the attention to detail from a hygienic perspective.
This will be seen as another important factor for factory inspectors/auditors.

CLEAN CHOICES

CLEAN CHOICES

  • Alternative terminal box positions for foot-mounted motors.
  • Pharmaceutical grade polishing exceeding 0.5 microns.
  • Heaters - used to reduce condensation and keep moisture out. They also help keep windings and bearings within normal operating temperatures in low-ambient conditions.
  • Application specific drain plugs can be fitted when needed on request as a proven way of removing condensation from inside the motor.

CLEAN GEARBOXES

  • Smooth-bodied stainless steel gearboxes are available. Their uniform design makes them ideal for multi-stacking, or double ratio (back-to-back) is possible; achieving very low output speeds and high torques.
  • See our Stainless Worm and Helical Bevel Gears brochure for further details about the Marlin Stainless gearbox range.

CLEAN CUSTOMISATION

  • SPECIAL CONSTRUCTION TENV AND TEFC

    - Outside of standard powers
  • SPECIAL SHAFTS AND FLANGES INCLUDING SEW DRIVE END SOLUTION

    The standard IEC flange configurations are commonly required for the majority of pump, fan and gearbox applications. However, we are also able to produce special drive end flange and shaft solutions for customised machinery.
    One example seen in the photo is the solution for SEW Eurodrive who are a major supplier to the food and beverage industry. We can supply motors with the special shaft and flange required for this range of gearboxes to enable direct replacement without the need for adaptors.
  • WATER COOLED

    Stainless steel motors for extreme high ambient environments and where more compact and high powers are necessary. More cooling equals more power.
  • PAD MOUNT

    for fan applications. Typical example is for vertical shaft down fans for funnel freezers where the motor is central in the airstream.

OPTIONAL ENHANCED SEALING ARRANGEMENTS FOR EXTREME APPLICATIONS

Experience has proven that enhanced sealing techniques can dramatically extend the motor's lifetime in extreme applications and mounting conditions, predominantly vertical shaft up. Magnetic sealing systems with precise labyrinth clearances are available for such arduous applications. These compact precision lapped, face contact, mechanical seals give bi-directional protection where 100% positive seal protection is required with or without shaft rotation. This is very important to precent pooling issues in shaft up applications when stationary or cooling back. They create zero shaft wear, prevent lubraication loss, eliminate contamination (solids, liquids and steam), have self-aligning faces and increase the equipment MTBF (Mean Time Between Failure).

Encapsulated compound complexity moulding and protecting the connections inside the terminal box with IP66 glands and bespoke flying leads to customers required specification.

Optional increased protection to IP69K for TENV motors. In the IEC 60529 rating system, IP6# refers to the product's ability to resist ingress of dust whereas IP#9K refers to the product's ability to resist ingress from high temperature (steam)/high pressure water.

CLEAN IN PLACE

When food, beverage or pharmaceutical production plants are washed down, the motors are subjected to high pressure jets of sometimes high-temperature water, or aggressive cleaning agents. Dependent upon the severity of this washdown, many consequences can occur including failure of the motor on start up through ingress of water, corrosion of exterior or internal parts if using standard alloy or cast iron mterial and potential for paint flaking and contaminating the final product itself.
