The mobile ventilation and cooling units from Tolsma-Grisnich are delivered as plug & play products.

The Keyhole Cooler is a cooled system which moves product through at an adjustable rate depending on process needs. This cooler is commonly used as part of a blanch-cool-cook process for the production of potato flakes

The Kelstream Scraped Surface Heat Exchanger is a vertical heat exchanger used for inline heating and/or cooling of medium to high viscous products, like mashed potatoes.

The new ‘Air Control MAX’ fan for (potato) storage ventilation is innovative on 3 features: 36% reduction in noise level, Up to 35% fewer r.p.m., Air output up to 7% higher.

The Tolsma-Grisnich fans are developed and produced in-house and are unique in its kind. The fans are designed to ensure a long life and a high efficiency.

Refrigeration Systems achieving optimal storage efficiency was the goal in developing this direct cooling system, so minimal drying-in and energy saving are crucial

Thermax is a leading manufacturer of vapour absorption chillers in the world. Vapour absorption chillers can be a viable alternative to conventional cooling solutions in the potato industry.

A Freon-based racking system is an industrial refrigeration solution using multiple compressors for efficient, reliable cooling. It preserves perishable goods, is cost-effective for medium loads, and ensures continuous operation across food, healthcare, and industrial applications.

The Ambient Air Cooler is a product cooling system designed to quickly cool foods, halting the cooking process and reducing their temperature for packaging.

The Wooden Constructions for Special Ventilation Systems, also known as pressure walls, are essential components for advanced agricultural storage facilities. These structures are designed to regulate airflow and maintain proper ventilation, ensuring crops like potatoes and onions remain fresh and high-quality during storage. 

NSSPL Modified Atmosphere Cold storage is used mainly for the storage of fresh vegetables. In this type of storage, a modified atmosphere is created and maintained.

The Callifreeze® is specifically designed to measure the LOF of individual products such as meat products, fish, vegetables, etc.

Wyma Hydro-Coolers quickly reduce the core temperature of fresh produce, extending shelf-life while preserving flavour and appearance.

The Screw Type Cooler cools the product down to the desired temperature to avoid retro-gradation at an adjustable rate depending on the process specifications.

FPS carton freezing solutions include two options, Carton Continuous Flow (CF) freezers and Variable Retention MultiPass (VRM) freezers, to fulfill a range of cooling, chilling, and freezing requirements with single and variable retention times.

Durable Z-Type wooden boxes for storing and transporting potatoes, carrots, and onions. Built from natural coniferous wood with strong fastenings, excellent ventilation, customizable sizes, export-ready, and ideal for passive or forced air storage systems.

Omnivent Letterbox Ventilation System offers precise, flexible airflow per row and layer, ensuring excellent drying and uniform air distribution. Ideal for onion sets, seed potatoes, and garlic in small to medium batches, it maintains quality and minimises weight loss.

NSSPL's blast freezer is engineered to achieve the highest efficiency and quality preservation levels. Our blast freezers quickly lower the temperature of your goods, preserving their flavour, nutritional content, and freshness. Whether working with seafood, meats, fruits, or vegetables, our technology guarantees rapid freezing, avoiding the production of frozen crystals to maintain texture and quality.
