The machines are pass-through tunnel machines and are designed to clean standard E1-E3 plastic crates with max. capacities of 450 or 600 crates/h. They consists of zones for pre-washing, main washing and rinsing.

Pre-washing and washing processes are performed in identical way – by centrifugal pumps and adjustable (by hand) nozzles. The washing agent is added manually in the tanks before starting the machine (option – automatic dosing system). They are equipped with manually cleaned filter for catching the bigger soils. The water for washing can be heated by electric heaters or an injector for direct steam. The desired water temperature can be adjusted between 30-60°C via thermostat. For the rinsing is used general water supply. After the rinsing this water is used also for refreshing and additional filling of the main washing tank.

The machines are designed for operation by single operator. The crates are placed on transport rollers with their bottom down over the machine. By pushing they are transported to the turning mechanism from where they enter in the washing zone. The further transport is done by motor driven transport chain. For washing of crates with different heights the rollers of the turning mechanism can be manually adjusted. Transport speed in the machine is smoothly adjustable. The gear motor is equipped with sliding connector to prevent eventual injuries to the personnel.

The control panel can be mounted either on the left or on the right side of the machine – in accordance with the customer requirements.
