‘Check & Detect’ specialist Loma Systems recently launched its new CW3 RUN-WET Combo and CW3 RUN-WET Checkweigher systems.

The move follows increased demands from food manufacturers for improved hygiene and cleaning efficiency for inspection equipment, as well as reduced machinery downtime due to frequent, harsh washdown regimes.

With both being fully IP69 rated and designed with the aim of following the latest principles for optimum hygiene standards, Loma’s CW3 RUN-WET Combo provides a combined checkweigher and metal detector in one, whereas the CW3 RUN-WET Checkweigher is a standalone checkweigher system.

According to the company, with current inspection systems, costly production delays can often occur as a result of difficult cleaning and waiting for the equipment to dry. Unprotected sensitive electrical parts of machines often need to be ‘bagged’ prior to washdown to prevent any kind of water ingress - one of the most common causes of system and component failure.

Furthermore, Loma says that certain checkweigher and metal detection systems are not suitable for high-care food production environments, where hygiene standards are highest and harsh washdown cycles are frequent. This lack of cleaning efficacy reportedly means that bacterial contamination in food remains one of the biggest causes of product recall.


Loma claims that by producing a far more sanitary design that is both quicker and easier to clean, the risk of bacterial contamination can be minimized, thereby increasing food safety and satisfying the strictest codes of practice and food safety standards.

Created with the goal of withstanding harsh, high-pressure and high-temperature deep cleaning regimes, the systems are suitable for high-care food environments, such as protein, dairy produce, meat, fish, and convenience food.

Following many of the EHEDG guidelines, the RUN-WET Combo and Checkweigher systems offer a host of new features and smart design techniques. They include easier-to-wash frames that use surfaces for quicker water run-off, minimal welds and reduced contaminant traps for optimum deep cleaning, with reduced risk of water ingress.

Removable top panels provide access to clean the conveyor belt without compromising safety, and enclosed motors, controls and pneumatics are all high-pressure and high-temperature washdown proof to IP69 rating.

In addition, the systems require no drying time following cleaning; this immediate start functionality apparently improves overall equipment effectiveness, helping to provide fast-paced food manufacturing and processing facilities with valuable gains in production time and cost savings.
