Hazardous Waste Solutions
We specialise in providing hazardous waste services including the safe removal, transportation, recycling, recovery, disposal, and secure destruction of various hazardous and problematic wastes, together with our mobile chemist services for the compliant listing and packing of your waste streams to meet your duty of care needs.

HAZID Studies
A Hazard Identification is a systematic and thorough method for ensuring that all significant hazards are considered and all potential accident triggering events are identified. The study identifies hazards from: Previous operational experience Effect of failure of equipment designed to protect, detect or mitigate hazards Human error

HAZOP Studies
Our HAZOP studies provide a systematic and collaborative evaluation of potential hazards within your plant or process. Our experienced facilitators will identify deviations, assess risk, and identify any gaps in your risk management—delivering a clear, actionable report designed to allow you to strengthen safety, support compliance, and optimise operational performance.

Heat circulation thermostats | KISS • Compatible Control
Heat circulation thermostats are specially designed for temperature control of externally attached applications with a small volume. The devices are fitted with bath vessels made of stainless steel or transparent polycarbonate and have rear-side pump connections as standard as well as a stainless steel bath cover with a filling opening. All models are fitted with an overtemperature and low level protection system according to safety class III/FL (DIN 12876) for use with flammable fluids. A powerful pressure-suction pump ensures optimal heat transfer to external attached applications.
Heat Exchanger Refurbishment
Our state-of-the-art refurbishment centre allows our trained engineers to test and restore heat exchangers. When heat exchangers begin to show signs of wear, our refurbishment services aim to restore equipment performance and extend asset lifespan. This may involve repairing, upgrading, or reconditioning components to bring them back to optimal operating condition. Refurbishment offers a cost-effective alternative to full replacement, helping chemical facilities improve reliability while controlling capital expenditure.

Heat Exchanger Servicing & Maintenance
We are proud to staff a large team of in-house, experienced service and NDT engineers, who are able to maintain your heat exchangers. Regular servicing is essential to ensure heat exchangers continue to operate safely and efficiently. Our comprehensive service and maintenance support, including inspection, cleaning, and preventative maintenance, aims to identify potential issues before they impact production.

Heat Exchanger/Pasteuriser Integrity Testing
Moody Heat Exchangers conducts integrity testing to assess the structural condition and reliability of your heat exchanger. Using advanced inspection techniques, their engineers can detect issues such as corrosion, leaks, or material degradation that could compromise performance or safety. These assessments allow operators to make informed maintenance decisions and ensure equipment continues to meet operational and regulatory standards. We provide two methods of integrity testing. Firstly, the GasTest 3000. This test uses the advanced Hydrogen gas to not only detect defects on a micron level but to identify any future weaknesses in your plates and gaskets. This can be vital when implementing a preventative maintenance plan. Secondly, the PasTest 2000 also detects defects, by circulating water around your plates to identify cracks. We provide both services to give you the option to choose the most suitable test for your heat exchangers and overall production.

Heating container
Our heating containers offer versatile temperature control and mixing: choose thermal fluid circulation or integrated heating cables for reliable heating. External thermal fluid connections enable both heating and cooling. Integrated mixer ensures uniform product quality. Optional polyurethane insulation.

HELICAL PUMPS
Flow rate ≤100,000 l/h Viscosity ≤ 100,000 cPs Pressure ≤ 24 bars Sanitary and Industrial Pumps Atex Certification Positive displacement helical pump High suction power Reversible Flow Flow rate proportional to speed Constant flow without pulsations High efficiency Pumps available with 1, 2, and 4 stages Materials according to application requirements.

Hellma 3 in 1 flow cell
The Hellma 3 in 1 flow cell is ingeniously engineered, compact and more capable than any other cuvette! Crafted from finest quartz, with black quartz masking, and fully fused monolithic construction, the 3 in 1 is physically tough, with high chemical and temperature resistance; it is even autoclavable! Hellma’s quartz cold-casting technology has enabled our engineers to sculpt the head of the cell to include quartz M6 screw threads for a secure flow connection, fused into the same single monolith, the cell is leak proof under pressure to at least 5 bar! Ergonomically designed with 4 apertures creating 2 perpendicular light paths, each with a different path length, it can be rotated in place to change path length with a simple twist, while still connected to the eluent flow, used as a standard transmission cell with variable path length and for orthogonal fluorescence measurements, it even has a locator dot for ease of alignment tracking. Ideal for tablet dissolution analysis – as absorbance increases over time, with a simple 90-degree rotation the path length can be reduced to boost your instrument sensitivity. Perfect for use with a dissolution cuvette array, the variable path length is sensitive enough to test precious, low concentration pharmaceutical analytes!

Hellma 3A Excalibur transmission Probe
Enhancing Process Safety and Quality Whether food, pharmaceutical or synthetic, reliable and precise monitoring of a process is essential for compliant production. Exceeding strict, mandatory USA "3-A" hygiene standards, and European EHEDG compliance, the Excalibur HY 25 (3-A) offers safe, compliant production while maintaining the precise and reproducible measurements.
