Electric air heater unit SH series

ACsingle-phasewall-mounted

Product Overview
PTC Air Heaters – SH Type: heat output is regulated by applied airflow; higher airflow increases heat output and power. High‑voltage SH variants available.

Highlights / Key Points

• Heat output proportional to applied airflow: increased airflow increases heat output and wattage.
• Available in two voltage groups: 200V–240V and 100V–120V.
• Standard models are highlighted for shorter lead times; customized wattage, length and specifications available for large orders.

Part Numbering
The part‑numbering scheme identifies model prefix (SH-), fin pitch code (M), insulation code (S or D), length and accessory codes. Graphics on the product page show positions for fin pitch, insulation and accessories.

Notes on Part Numbering

• PTC FIN PITCH (SH-XXXXM): Power (W) in tables is based on fin pitch 1.68 mm (code M).
• PTC INSULATION (SH-XXXXM-XXXS): Power (W) in tables is based on Single Insulation (code S).
• Double insulation (code D) typically increases price ~20–30% and reduces power by ~10%; double‑insulated units have no electrode potential on fins and suit conductive contact, high humidity, impact resistance or automotive quality requirements.
• For units with Maximum Inrush > 14 A, certain accessory codes may exclude a thermostat by default.

Accessories

• PTC + Mounting Frame — temperature‑resistant plastic frames (examples: MSHF-70 for 70 mm, MSHF for 70 mm, MHF-90 for all lengths).
• PTC + Frame + Fan + Accessories — optional assembled heater assemblies can include a PTC heater (e.g. SH 70 mm), plastic frame(s) (MSHF-70), a standard 92×92 mm ball‑axial fan, thermostat, fuse, terminal wire set and screws; part numbers indicate assembled vs separate options.

3D / CAD / Models
3D viewers are available for SH and SHW Types; STEP/3D files can be provided on request for project integration.

Specifications (overview)
Specification tables for 200V–240V and 100V–120V list Power (W) based on fin pitch 1.68 mm (M) and single insulation (S). Double‑insulated (D) units have ≈10% less power than single‑insulated values. Standard models are highlighted for faster delivery; custom designs possible for larger quantities.
