Product Description

Detergent and Rinse Aid do different jobs inside a Commercial Dishwasher, so they should not be dosed in the same way.

The Hengze Warewash Dispenser uses two separate pumps to control detergent and rinse aid independently. This gives operators and installers more control over chemical delivery while reducing the need to measure and add chemicals manually during daily operation.

Dosing can be controlled down to 1 ml. Pump speed and operating time can also be adjusted to change the amount of chemical supplied. The detergent side operates at 60 rpm with a flow rate of 180 ml/min, while the rinse-aid side offers 0–30 rpm and 0–60 ml/min adjustment.

For different dishwasher programs, both the pump delay and running time can be set from 0 to 99 seconds. This makes the Dishwasher Dispenser easier to configure around different wash cycles, chemical concentrations and operating conditions.

Available in AC 110/120V and AC 220V, 50–60 Hz, the unit can be supplied for commercial kitchen projects in different markets. As part of Hengze's range of Commercial Dishwasher Parts, it is built with serviceable pump components for easier routine maintenance.

Under appropriate installation and maintenance conditions, the expected service life can reach approximately 6 years, while some customers have reported using their dispensers for up to 8 years.

Features

Separate Detergent and Rinse Aid Control

Two independent pumps handle detergent and rinse aid separately, allowing each chemical to be set according to its own dosing requirement.

Dosing Precision Down to 1 ml

The warewash dispenser supports chemical dosing control down to 1 ml, providing finer adjustment for professional dishwashing applications.

Adjustable Chemical Output

Pump speed and operating time can be adjusted according to the required dosage. A higher pump speed increases chemical delivery.

180 ml/min Detergent Pump

The detergent pump operates at 60 rpm with a rated flow rate of 180 ml/min, providing the higher output needed for detergent feeding.

0–60 ml/min Rinse Aid Pump

The rinse-aid pump operates from 0–30 rpm, providing an adjustable flow range of 0–60 ml/min.

0–99 Second Delay Setting

The pump does not have to start immediately. A 0–99 second adjustable delay helps coordinate chemical feeding with different dishwasher operating sequences.

0–99 Second Run Time

Pump running time can also be set between 0 and 99 seconds, giving installers another way to fine-tune chemical delivery.

110/120V and 220V Available

Different electrical configurations are available for overseas projects: AC 110/120V or AC 220V, 50–60 Hz.

Serviceable Pump Design

Pump tubing and applicable wear components can be inspected and replaced during routine maintenance instead of treating the complete unit as a disposable component.

Built for Long-Term Commercial Use

Expected service life can reach approximately 6 years under suitable operating and maintenance conditions. Some customers have reported units remaining in use for up to 8 years.

Technical Specifications

Applications

The Hengze warewash dispenser is intended for professional dishwashing systems where detergent and rinse aid need to be automatically supplied during daily operation.

It is particularly useful for restaurants, hotels, cafés, bakeries, catering kitchens, central kitchens, school canteens, factory cafeterias and other commercial foodservice operations.

The dispenser can be considered for compatible professional dishwashing equipment requiring an external chemical dosing system.

For commercial kitchen contractors and equipment dealers sourcing commercial Dishwasher Parts, the unit can also be supplied as a separate component for compatible warewashing projects.

Compatibility should be checked according to the dishwasher's voltage, frequency, control method and chemical dosing requirements before installation.

Support and Services

Chemical dosing should be set around the actual dishwasher rather than using the same setting for every installation.

Hengze can assist with voltage selection, dispenser matching, connection guidance, pump timing and initial dosing adjustment according to the customer's dishwasher and chemical requirements.

For ongoing maintenance, pump tubing and applicable wear components can be checked and replaced when necessary. Suitable commercial dishwasher parts can also be discussed according to the equipment configuration.

For a complete Hengze warewashing project, customers can source the dishwasher, dispenser, detergent and rinse aid together, making it easier to match the equipment and chemical dosing system.

OEM and distributor requirements are also available for discussion based on purchasing quantity and market requirements.

Packing and Shipping

The dispenser is packed to protect the ABS housing, pump assemblies and internal components during storage and transportation.

Before placing an order, customers should confirm the required electrical version:

AC 110/120V — 50–60 Hz
AC 220V — 50–60 Hz

For bulk orders, carton packing, palletizing, private labeling and other packaging requirements can be discussed according to quantity and destination.

The dispenser can be shipped separately as one of the required commercial dishwasher parts, or together with Hengze commercial dishwashers and related warewashing accessories for complete project orders.
