Peripheral equipment for processing polyurethane

Equipment for processing, conditioning and storing raw material systems as well as processing polyurethane products

Hennecke offers its customers a broad portfolio of peripheral equipment. These are used, for example, when raw material systems are to be conditioned through the targeted addition of different components. Moreover, Hennecke is able to offer tried and tested equipment for temperature control or the mechanical processing of polyurethane products as well as systems for intelligent and secure raw material storage.

Raw material processing and conditioning

Peripheral equipment for adding gas and blowing agents, plus raw material conditioning & manipulating systems

For the end product to achieve the desired properties, it will be necessary in some applications to condition the raw materials through a metered addition of specific gases, blowing agents or solids such as nitrogen, natural carbon dioxide, pentane or calcium carbonate. For this, Hennecke offers proven peripheral equipment designed to deliver desired production results with both economic and ecological benefits. At your request, our machinery and equipment can also be supplied with conditioning and manipulating systems for the raw materials used to control performance properties through the metered addition of fluids and/or solids.

PENTAMAT

Premixing station for the reliable metered addition of blowing agents such as pentane

Pentane (hydrocarbon) is an environmentally compatible blowing agent that eliminates the need for using CFCs in rigid and integral skin foams production. Instead of metering the blowing agent directly into the mixing chamber, the addition of pentane takes place batch-wise within a carrier...

LAMBDAMAT

Premixing station for the precise metering of HFOs (such as Solstice® LBA) and other blowing agents in batch processing.

The LAMBDAMAT blowing agent metering device from Hennecke offers customers a precise and reliable premixing station for loading the blowing agents of the polyurethane components in a batch process. Here the LAMBDAMAT is primarily designed for the application of HFOs (hydrofluorolefins) and...

CARBOMAT

Metering unit for CO2 loading in a batch process

The effective pre-expansion of the reactive mix (froth effect) is of special advantage to flexible polyurethane foam applications. Additions of very small amounts of CO2 are particularly appropriate. Hennecke's CARBOMAT unit is a blowing agent metering unit for charging...

AEROMAT

Metering unit for charging the polyol component with gas

The release of very fine gas bubbles into the reactive mix – known as nucleation – is responsible for cell formation and for the final cell structure of foamed polyurethane products. The gas charge on the polyol side is thus indispensable for certain PU applications. When producing...

HT30evo

Piston metering device for processing filler-containing additional components

Users who are looking for a system for processing abrasive pigments, chemically aggressive additives or additional components containing fillers can take advantage of the HT30evo as an efficient metering unit for a wide range of possible applications. Hennecke is offering the extremely compact...

Additive processing

Metered addition of liquids and processing of solids

The properties of polyurethane systems can be significantly improved by a wide variety of liquid and solid additives. While raw materials are prepared in a batch process, sometimes liquid additives such as flame retardants have to be metered into the mixhead directly online, or into the flow...

Melters

Equipment for liquefying highly viscous raw materials and granulates

Raw materials are often introduced in solid form during elastomer systems processing. This means that they have to be liquefied in the metering machine before they are processed further. For materials stored in drums, Hennecke offers melting chambers. Different types of granulates are...

Chillers

Exact temperature control by water-cooling systems

Depending on the application, a polyurethane system often requires exact temperature control methods. Hennecke offers circulated-water industrial chillers of types and dimensions corresponding to the pre-calculated heating requirements of your particular raw materials system.

IBC station

Modular plant concept with innovative detail solutions for integrating IBC’s in PU production

The new, modular IBC station from Hennecke greatly simplifies handling of the containers, ensures utmost process reliability and also offers an attractive price-performance ratio due to standardization and series production. In addition to a consistently modular construction, the plant concept...

VACUMAT

Efficient double degassing system for effective evacuation of raw materials

In order to produce polyurethane products with a compact structure, dissolved gas must be removed from the raw material. Hennecke's brand new VACUMAT double degassing system safely removes the residual gas from the raw material. The VACUMUT operates under full vacuum and has two degassing...

Product conditioning

Equipment and systems for handling polyurethane products

When polyurethane systems are processed, many products require special handling before and after the actual metering operation. Hennecke offers you custom equipment perfectly suited to your process and adapted, through temperature control or mechanical treatment, to your particular system’s technology.

Pre- or post-heating ovens

Temperature control units for upstream or downstream tempering processes

Various polyurethane products need to be further tempered after being demolded. In case of product combinations – regardless of whether materials are homogeneous or a mix of materials or plastics – it is often necessary to preheat the insert or core. For these tempering processes,...

Crushers

Mechanical and pneumatic crushers for opening up foam cells

Polyurethane flexible foam products such as car seats or upholstered furniture, as well as many other molded foam cushioning products, require foam cells to be broken up immediately after they are demolded. Hennecke offers two options for this--roller crushers, which are used for molded parts...

Storage

Intelligent and safe raw material storage

Tank farms and IBC stations

Intelligent and safe raw material storage

The reactive polyurethane components and potential blowing agents are safely stored in tank farms and stations for IBC's (Intermediate Bulk Container) that are manufactured and installed in compliance with the applicable EU directives. The storage facilities and stations supplied by...
