MKS Instruments® Series 48 Heaters for Single-Use Filters with NEMA 4 Control Unit Enclosures are a cost-effective and low maintenance solution for biopharmaceutical processes requiring superior thermal control. Series 48 heaters prevent vapor condensation in single-use capsule vent and process filters. Series 48 heaters offer tight temperature control and advanced functionality, while complying with strict safety regulations.

Series 48 heaters feature a unique control system which integrates a temperature process controller, a high-low temperature alert, and power switching with a safety high limit - all inside a NEMA 4X enclosure. The controller features a user-friendly digital display and an optional Modbus® RTU Communications module allows users to remotely adjust parameters through its RS485 interface.
