Therm Products Spa Heater for Arctic Spas 48-9120-7P-K

HydroQuip 48-9120-7P-K | 5.5kW Titanium Arctic Spa Replacement

The 48-9120-7P-K is built for extreme durability. Because Arctic Spas are often located in harsh northern climates and may use salt-based sanitizers, this heater comes standard with a Titanium element. Titanium is virtually immune to chemical corrosion and "pitting," making it far more reliable than standard Incoloy elements in high-demand environments.

Key Features

• Titanium Heating Element: The "gold standard" for longevity. It is resistant to salt, high chlorine levels, and poor pH balance.

• Arctic Spa Specific Design: A 12-inch straight flow-thru manifold that matches the plumbing footprint of Arctic and Coyote Spas perfectly.

• High-Output Performance: Rated at 5.5kW @ 240V for rapid heating, even in freezing ambient temperatures.

• Plug-and-Play Wiring: Includes a 48-inch power cord with spade connectors (ring terminals) designed to connect directly to the spa's circuit board.

• 316L Stainless Steel Housing: The 2.25" diameter tube is made from high-grade stainless steel to prevent rust and internal scaling.

Technical Specifications

Technician's Note

This unit includes a threaded tap for a pressure switch, but the pressure switch itself is not included. When replacing an Arctic Spa heater, it is common practice to also replace the pressure switch (usually a Tecmark 3902) to avoid "FLO" errors on the topside control panel.
