The Seko WareDose 35 is a compact peristaltic dosing unit designed for single-machine commercial dishwasher and glasswasher installations. It manages both detergent and rinse aid dosing from a single housing, and incorporates a conductivity probe that monitors wash solution concentration continuously, adjusting dosing output in real time rather than working to a fixed timer cycle.

Chemical dosing is one of the more easily overlooked variables in warewashing, but it has a direct impact on hygiene compliance, wash results, and running costs. Timer-based systems are common and straightforward, but they cannot account for changes in water conditions, load variation, or shift patterns. When concentration drifts, the consequences range from poor wash results through to unnecessary chemical spend. The WareDose 35 addresses this by measuring actual conductivity in the wash tank and dosing accordingly — maintaining consistent levels across the full service period without manual intervention.

From an operational standpoint, the unit offers several practical advantages:

• Conductivity-controlled dosing holds concentration steady, reducing chemical waste and running costs
• Microprocessor control with LED display allows straightforward on-site programming and adjustment
• Peristaltic pump mechanism is inherently reliable; tubing is the only wear item and can be replaced without specialist tools
• Dual-pump configuration handles detergent and rinse aid from one compact unit, keeping the installation tidy
• Compact housing suits sites where space around the machine is limited

Installation involves mounting the unit in close proximity to the warewasher, routing the chemical tubing to the relevant containers, and fitting the conductivity probe in the correct position on the machine. Probe positioning and connection points vary between warewasher models, so compatibility with the specific machine should be confirmed before ordering. The WareDose 35 is intended for single-machine use; operations running multiple machines simultaneously or with sustained very high throughput may find a higher-capacity dosing solution more appropriate.

This unit is well suited to cafés, restaurants, pubs, hotel bars, and contract catering sites operating a single commercial dishwasher or glasswasher where reliable chemical control and cost management across long or busy service periods matter. Smaller operations using a basic timer-based unit may find the conductivity probe adds meaningful value over time, particularly where water hardness or usage patterns vary.

If you want to check compatibility with your existing machine or talk through your warewashing chemical setup before going ahead, our team is happy to work through the details with you.

The Seko PR1 is a peristaltic dosing pump designed to deliver rinse aid consistently to commercial dishwashers and glasswashers. Rather than using valves or internal seals in direct contact with the chemical, the peristaltic mechanism works by squeezing fluid through a flexible tube. This approach is inherently well suited to handling rinse aid concentrates, which can degrade conventional pump mechanisms over time.

In day-to-day kitchen use, consistent rinse aid dosing has a direct bearing on glass clarity, drying performance, and how quickly spotting or streaking appears on crockery and glassware. The PR1 allows flow rate to be fine-tuned via a trimmer dial, enabling calibration to suit both the machine's cycle timing and local water hardness — two factors that vary considerably from site to site. Once the correct setting is established, tamper protection plugs prevent accidental adjustment by kitchen staff, which is a practical consideration wherever multiple people work around the machine.

• Adjustable flow rate via trimmer dial to match machine and water conditions
• Tamper protection plugs hold calibrated settings during service
• Peristaltic mechanism limits chemical contact with pump internals
• Low power draw suits continuous full-day operation
• Compact form supports both wall mounting and in-machine installation

The pump can be wall mounted close to the machine or fitted internally within most warewashing equipment, and it runs from a standard electrical supply with minimal power draw. It is compatible with the majority of commercial dishwashers and glasswashers, whether as a replacement for a worn unit or as an upgrade to an existing dosing arrangement.

The PR1 is commonly used in pubs, restaurants, hotels, and contract catering operations where reliable rinse aid delivery is a routine requirement. If you are fitting this to a specific machine or want to confirm the flow range suits your setup, the team is glad to talk it through before you order.

The Seko PR4 is a peristaltic dosing pump designed to deliver liquid detergent to commercial dishwashers and glasswashers at a controlled, consistent rate. Peristaltic pumps work by compressing a flexible internal tube to move fluid, which keeps the chemical entirely isolated from the pump mechanism. This reduces wear on internal components and makes the unit practical to service without specialist tools.

In a commercial warewashing setup, accurate chemical dosing has a direct bearing on wash quality and running costs. Underdosing results in poor wash performance; overdosing wastes chemical and can interfere with rinse quality. The PR4 addresses this with an analogue speed adjustment that allows the dosing rate to be set precisely for the machine and detergent in use. Once the correct rate is established, tamper protection plugs can be fitted to hold the setting — a sensible precaution in busy kitchens where accidental adjustment is a genuine operational risk.

• Adjustable output suits different detergent concentrations and machine demands
• Chemical isolation from the pump mechanism reduces maintenance requirements
• Compatible with wall mounting or internal fitting within most warewashing equipment
• Simple trimmer adjustment keeps commissioning time to a minimum
• Tamper protection maintains consistent dosing once the rate is confirmed

Installation is straightforward for a qualified engineer. Correct positioning relative to the detergent container and the machine draw point is important for reliable priming, so it is worth planning the installation carefully before fitting. If you are switching detergent products or moving from a different dosing system, confirming viscosity and concentration compatibility with your chemical supplier beforehand will save time.

The PR4 is well suited to single-site operations running one or two warewashers where a reliable, adjustable dosing solution is needed without the complexity of a larger system. Sites running multiple machines or processing higher chemical volumes may be better served by a higher-capacity dosing arrangement.

If you are not certain whether the PR4 is the right match for your machine or detergent, our team is happy to talk it through before you place an order.
