What Western Tydens does

Western Tydens Limited is a privately held UK industrial machinery manufacturer that has been producing diesel engine exhaust safety systems at its factory in Ivybridge, Devon, for over 40 years since its founding in 1983. The company serves industrial diesel engine operators across Europe whose applications involve hazardous or potentially explosive atmospheres, where spark arresting and overspeed protection are safety or regulatory requirements.

The company's product portfolio is anchored by ATEX-approved Spark Arrestors, offered in three variants: the NT range for ultra-low back pressure on modern low-emission engines, the WT2L twin centrifuge range for conventional engines with integrated silencing, and the WT1L single centrifuge range for temporary auxiliary use. Additional offerings include air intake shutdown valves that automatically stop diesel engines upon flammable gas ingestion, standard and bespoke silencers, catalytic converters, exhaust purifiers, diesel particulate filter cleaners, pipework, elbows, and exhaust accessories. Manufacturing is supported by an in-house design department using 3D CAD and Computational Fluid Dynamics (CFD) software, with a deliberate specialisation in bespoke one-offs and small batch production.

Western Tydens operates a sales-led go-to-market model, selling directly to UK customers via telephone and email and reaching overseas markets through international distributors. Pricing is quote-based due to the non-standard nature of much of the production, and revenue is generated entirely through hardware sales. The company maintains a limited digital presence (website, Facebook, Twitter, LinkedIn, email newsletter) and is independently owned with no disclosed institutional investors, parent company, or external capital raises.

Functional benefit

Brands

• ATEX Spark Arrestors: ATEX approved spark arrestors for diesel engines, including NT Spark Arrestors (ultra-low back pressure range for modern low emission diesel engines), WT2L Spark Arrestors (twin centrifuge range for conventional diesel engines with silencing properties), and WT1L Spark Arrestors (single centrifuge auxiliary range for temporary use).

Products and services

• ATEX Spark Arrestors ATEX approved spark arrestors designed for diesel engines, available in three main types (NT, WT2L, WT1L) with a bespoke design and manufacture service for customers needing non-standard configurations. Intended for industrial diesel engine operators in potentially explosive atmospheres.
• NT Spark Arrestors Ultra-low back pressure spark arrestor range designed for permanent installation on modern low emission diesel engines. Targeted at industrial operators needing compliant spark arresting with minimal engine performance penalty.
• WT2L Spark Arrestors Twin centrifuge spark arrestor range designed for permanent installation on conventional diesel engines, also offering good silencing properties. For industrial diesel engine operators requiring combined spark arresting and noise reduction.
• WT1L Spark Arrestors Single centrifuge auxiliary spark arrestor range intended for temporary use as an addition to existing exhaust systems, for industrial diesel engine operators requiring supplemental or short-term spark protection.
• Shutdown Valves Air intake valves designed to automatically shut down a diesel engine should overspeeding occur due to the ingestion of a flammable gas or vapour. Targeted at industrial diesel applications needing automatic overspeed protection.
• Exhaust Silencers Standard range of exhaust silencers designed to suit most silencer requirements for diesel engines. Custom designs can also be manufactured from customer drawings or patterns for industrial buyers with non-standard needs.
• Bespoke Silencers Custom silencer design service using the latest 3D CAD software to ensure the finished silencer design meets exact customer specifications. For industrial diesel engine operators requiring non-standard silencing solutions.
• Catalytic Converters Exhaust treatment products for diesel engines designed to reduce emissions. For industrial diesel engine operators needing emission control solutions.
• Exhaust Purifiers Equipment for purifying diesel engine exhaust. For industrial diesel engine operators requiring exhaust after-treatment.
• Diesel Particulate Filters Cleaners Products for cleaning diesel particulate filters as part of diesel engine exhaust maintenance. For industrial diesel engine operators needing to maintain DPF performance.
• Pipework, Elbows, and Exhaust Accessories Supporting components for diesel exhaust systems, including pipework, elbows, and various exhaust accessories used to complete an exhaust safety installation. For industrial diesel engine operators and installers.
