Birchmeier is a leading manufacturer of spraying, foaming, and dosing equipment and will celebrate its 150th anniversary in 2026. Its extensive product range extends from small hand-held sprayers to backpack and wheelbarrow sprayers for different applications. The focus is on quality “Made in Switzerland,” functionality, and reliability of the products. All devices are developed and produced in the company's own factory in Stetten (Switzerland). The products are exported to over 80 countries.

Patented TelRo set - Low-pressure solution for facade and window cleaning

Low pressure instead of high pressure
Cleaning agent is fed from a battery-powered sprayer into the telescopic lance via the hand valve and applied through a low-pressure nozzle. Compared to high-pressure systems, chemical consumption and liquid volume are reduced. This reduces the effort required for collecting and disposing of the wastewater and simultaneously minimizes the impact on sensitive surfaces.

Easier work
The combination of an easy-grip hand valve and a stable attachment to the telescopic lance ensures safe handling of the lance when working at heights. The valve automatically dispenses the cleaning fluid. There's no need to juggle the lance, valve, and hose simultaneously.

Quick conversion
The hand valve comes with two mounting rails that are permanently attached to the telescopic lance. This allows the TelRo hand valve, and therefore the sprayers, to be quickly and easily changed between different telescopic lances. Various applications can thus be 
completed with short changeover times. This increases the flexibility of existing equipment and minimizes on-site setup time.

Advantages at a glance
- Intuitive use of the TelRo system
- Reduced changeover times for lance and tool changes, resulting in faster, more efficient workflows
- Improved ergonomics, as simultaneous handling of the lance, valve, and hose is no longer necessary
- More stable guidance of the telescopic lance
- The low-pressure cleaning process puts less strain on surfaces and also reduces waste disposal.
- Both the nozzle holder and the TelRo hand valve mounting rails are designed to fit different telescopic lance diameters.

TLK 35 battery compressor replaces the classic hand pump

The TLK 35 eliminates the need for manual repumping, enabling continuous operation without physical effort. Thanks to its high air output, the battery compressor builds up pressure very quickly. It can even be used to operate foam and powder pressure storage devices without any loss of performance throughout the entire contents of the container. 

Unlike hand pumps, where pressure inevitably drops, the TLK 35 uses electronic technology to maintain a constant working pressure. Users can freely select the pressure within a range of 0.5 to 3.5 bar. The result is a consistent output and a defined spray pattern with a homogeneous droplet size. A clearly visible LED display provides information about the operating pressure used and the current charge status.

Power is supplied via the manufacturer-independent CAS interchangeable battery system. Compatible with batteries from 2 Ah to 10 Ah, the TLK 35 offers flexible running times. Thanks to its intelligent control system, the pump only runs when needed (“pump-on-demand”), which maximizes the range per battery charge.

With the development of the TLK 35, Birchmeier is launching a new generation of devices called the e-line. The series includes various models for different applications—from spraying and foaming to dusting—and thus offers a wide range of uses for a variety of professional requirements. The manufacturer's hand-operated three-, five-, and seven-liter plastic pressure storage devices can be retrofitted with the powerful compressor—in line with the principle of sustainability.

Optimal chemical output for facade cleaners

The TelRo system addresses key challenges in professional facade and window cleaning by replacing complex high-pressure methods with a controlled low-pressure approach. It improves ergonomics when working with long telescopic lances, allows secure one-hand operation of lance and valve, and enables fast, tool-free switching between different telescopic lances. This results in greater efficiency, reduced chemical use, less surface stress, and improved working comfort on site.

The TLK introduces the new e-Line generation of devices, which includes devices for spraying, foaming and powdering.

The TLK 35 upgrades manual pressure sprayers to electronically controlled, battery-powered systems. Instead of manual pumping, it maintains a constant pressure of 0.5–3.5 bar for reproducible spray patterns and precise dosing. The high air output enables reliable spraying, foaming, and powdering without any loss of performance. Since no air cushion is required, the usable filling volume increases and the refill frequency is reduced. CAS batteries (2–10 Ah) and the demand-controlled pump function
