Product catalog summary

Overview
Sinus Jevi specializes in the design and manufacture of electrical duct heaters for various applications, including climate control, heat generation, and ventilation systems. Custom solutions are available for specific needs such as grain dryers, process systems, ships, and high-temperature environments.

Specifications

Materials: Standard heaters are made from hot-galvanized steel, with options for other materials upon request.
Heating Elements: Made from AISI 304 stainless steel, with a surface load of 2.5 W/cm² for air velocities above 2 m/sec. High-temperature elements use AISI 309/Inconell.
Overheating Protection: Includes a built-in thermolimiter with automatic reset and a fire thermostat with manual reset.
Temperature Regulation: Recommended to use a multistep control device; heaters below 16.5 kW can use electronic control.

Standard Designs

EFFK Series: Available in various outputs and configurations, suitable for 3 x 400 V-Y~ systems.
EFR Series: Designed for 230 V systems, with options for different diameters and outputs.

Special Designs

EFF: Rectangular duct heaters for ventilation and process systems, customizable in materials and terminal box densities.
EFRS: Similar to EFF but for round ducts.
EFFL: Includes airflow between the terminal box and duct piece, used at temperatures above 70ºC.
EFI: Inset heater for existing ducts, removable without duct removal.

Explosion-Proof Heaters
Sinus Jevi offers a range of explosion-proof heaters compliant with ATEX, IECEx, and EAC directives. The production is certified by TUV-Nord, and the company adheres to ISO-9001 and ISO-14001 standards.
