Senasys Solutions in the Aquatic Industry

K-Kontrol Line Voltage Thermostats

K-Kontrol

Weatherproof Line Voltage Thermostats

K-Kontrols Weatherproof Line Voltage Thermostats are widely used in the aquatic industry to control air temperature in enclosed spaces such as filtration rooms, pump enclosures, and aquatic equipment housing. Known for their accuracy, these thermostats help maintain stable environmental conditions that are critical to aquatic system performance.

The durable, weatherproof housing protects against moisture, dust, and debris, making them a strong choice for the harsh conditions often found in aquatic facilities.

Snap Disc Thermostats

Senasys Snap-Disc 

Bi-Metal Snap Disc Thermostats

Senasys Snap Disc Thermostats are used in the aquatic industry to maintain consistent temperature control across systems such as aquariums, fish tanks, and aquaculture equipment. These thermostats activate or deactivate heating or cooling elements based on preset temperature thresholds, helping prevent fluctuations that could stress aquatic life.

The snap-action design offers fast, repeatable response, supporting stable water temperatures essential to fish health and system performance. Senasys Snap Disc Thermostats contribute to creating controlled environments that promote the health and longevity of aquatic species.

Stemco

Capillary Switches & Thermowells

Stemco Capillary Thermostats & Thermowells are used in the aquatic industry to regulate water temperature in systems such as hot tubs. These thermostats use a capillary tube to accurately position the sensing element in the water, allowing the control to respond precisely to temperature changes.

As water temperature rises or falls, the thermostat adjusts the heating element to maintain consistent conditions. This helps create a stable, comfortable environment while improving energy efficiency by preventing overheating. Stemco Capillary Thermostats support accurate temperature management in hot tubs and similar aquatic systems.

Pneumatic switches and controls

Presair

Pneumatic Switches & Controls

Presair Pneumatic Switches & Controls are commonly used in pools, spas, and aquatic systems to manage equipment such as jets, lighting, and heating elements. Designed for hands-free operation, these air-actuated switches offer safe and user-friendly control in wet or humid environments.

Built for durability, Presair switches perform reliably in both wet and dry conditions. Their water-resistant construction makes them well-suited for aquatic facilities where electrical safety and ease of use are priorities. These switches help streamline control of water-based features while supporting long-term performance.
