Technical advice and reliable components for complex process plants
Hans Buch helps companies in the process industry specify and source the right components and technical solutions – from pumps, valves and heat transfer to pneumatics, instrumentation, gas detection and automation.
Stable and forward-looking solutions for the process industry of the future
We combine products from a broad portfolio of specialised manufacturers and help select solutions suited to the process medium, temperature, pressure, capacity requirements and surrounding operating environment.
Our technical specialists provide advice for new plants, expansions and modernisations. We focus on creating stable processes, reducing the risk of breakdowns and making component selection and maintenance easier to manage.
For us, downtime is never an acceptable solution.
Maintenance and modernisation
When a component fails or is discontinued, a replacement must not only fit physically. It must also work together with the rest of the process.
Hans Buch helps with:
- Identification of existing and older components
- Replacement of discontinued pumps, valves, sensors and pneumatic components
- Alternative product choices in the event of long lead times
- Energy optimisation of pumps, compressed air and heat transfer
- Standardisation of components across plants and production lines
- Spare parts and components for ongoing maintenance
- Technical advice for conversions and capacity expansions
- Reduction in the number of different component types and suppliers
Transport and handling of liquids
Pumps and valves are central to a stable process. Incorrect sizing or material selection can lead to cavitation, leaks, unnecessary energy consumption and frequent operational stoppages.
Hans Buch helps with:
- Centrifugal pumps for the transport and circulation of process liquids
- Compressed-air-driven diaphragm pumps for chemicals, aggressive media and liquids containing particles
- Pumps for dosing, emptying, transfer and recirculationValves for shut-off, regulation and redirection of liquids and gases
- Pump and valve solutions for varying flow rates, pressures and viscosities
- Selection of materials, membranes and seals based on the chemical properties of the medium
- Technical advice on capacity, head, system resistance and operating conditions
Heat transfer and temperature control
Precise temperature control is essential in processes where products need to be heated, cooled, condensed or subjected to heat recovery.
Hans Buch can help with:
- Plate heat exchangers for heating, cooling and heat recovery
- Tube heat exchangers for demanding media and process conditions
- Solutions for reusing surplus heat and reducing energy consumption
- Valves and actuators for regulating temperature and flow
- Instrumentation for measuring and monitoring process and medium temperature
- Dimensioning based on the temperature programme, flow, pressure drop and medium composition
- We help find a solution that supports both the process requirements and the plant’s overall energy efficiency.
Pneumatics and process automation
Automated valves, cylinders and movements must operate precisely and repeatedly – also at high cycle rates and in demanding production environments.
Hans Buch can help with:
- Pneumatic cylinders and actuators for opening, closing, positioning and material handling
- Process and solenoid valves for controlling air, gas and liquids
- Valve terminals for centralised and decentralised control of pneumatic functions
- Air treatment units, regulators and filters for stable compressed air quality
- Electric actuators and servo motors for controlled positioning
- Proportional valves for precise regulation of pressure and flow
- Automation components for both new machines and modernisation of existing plants
We help dimension the solution based on force, speed, cycle time, stroke length and the available working pressure.
Measurement and process instrumentation
A process plant can only be controlled effectively when the critical process values are measured accurately and consistently.
Hans Buch can help with:
- Pressure and differential pressure transmitters
- Level instrumentation for tanks, vessels and process plants
- Temperature and humidity measurement
- Flow measurement and monitoring of liquids and gases
- Measurement of dew point, air quality and CO₂
- Instruments for non-contact temperature measurement
- Calibration equipment and tools for checking measuring instruments
- Sensors and transmitters for integration with the plant control system
We advise on the measurement principle, measuring range, accuracy, process connection, material composition and signal type.
Process and occupational safety
Gas leaks, overpressure and faults in process equipment can have serious consequences for employees, production and the surrounding environment.
Hans Buch can help with:
- Stationary and portable gas detection
- Measurement of flammable, toxic and oxygen-displacing gases
- Alarm and monitoring solutions for production and technical areas
- Pressure and level measurement for protecting tanks and process equipment
- Components for monitoring critical process conditions
- Signal transmitters and alarms for clear fault notification
- Product selection with relevant approvals for the specific installation
We help clarify which gases and risks need to be monitored, where the measuring equipment should be placed, and how the solution can be integrated with the plant’s other safety systems.
Chemical industry and aggressive process media
Chemicals, high temperatures and aggressive media place particular demands on materials, seals and construction.
Hans Buch can help with:
- Diaphragm pumps for acids, bases, solvents and other chemical media
- Valves and actuators for safe control and shut-off
- Components made from chemically resistant materials
- Seals and diaphragms selected according to the properties of the mediumInstrumentation for measuring pressure, level, temperature and flow
- Gas detection for monitoring potential leaks
- Technical advice on compatibility between the medium and the component
We take into account, among other things, concentration, temperature, pressure, particle content and the installation’s safety requirements.
Energy, utilities and environmental plants
Facilities within energy, utilities and the environment often need to operate around the clock and function under changing loads.
Hans Buch can help with:
- Pumps for circulation, transport and dosing
- Heat exchangers for energy transfer and heat recovery
- Valves and actuators for regulating process flowInstrumentation for measuring pressure, temperature, flow and level
- Differential pressure measurement for filters, ventilation and pipe systems
- Gas detection for plant rooms, process areas and enclosed installationsAutomation components for optimising and monitoring the facility
We help with new builds, capacity expansions and the replacement of older or discontinued components.
