Digital temperature control unit MedLine® TW-P

waterprogrammablefluid circulation

Overview
The MedLine® TW-P is a Thermolator (TW-P Series) designed for precise process temperature control using high-efficiency circulated water heated or cooled to the required setpoint. The package is intended for production and laboratory environments requiring reliable temperature stability and serviceable construction.

Key product summary
The MedLine® TW-P delivers accurate temperature control, durable three-piece cast construction, and tool-free access for maintenance. Standard components include Incoloy heater elements, silicon carbide pump seals, pressure gauges and microprocessor controls with clear process and setpoint display.

Features

• Built-in pressure gauges — standard on the TW Series for system pressure monitoring.
• Incoloy heaters — corrosion- and high-temperature-resistant heater elements to reduce chemical and thermal degradation.
• Three-piece cast construction — design that minimizes potential leak points.
• Built-in sediment trap — captures contaminants away from pump seals to extend seal life.

Control, pumps and performance

• Microprocessor controls — stable temperature control under varying loads; status indicators and simultaneous display of process supply and setpoint. Features include cool-down sequence, pump running-hours counter, temperature-deviation alarms, adjustable alarm delay, return-temperature toggle, alarm horn and silence switch, error diagnostics, and independent start/stop buttons.
• Higher-efficiency pumps — available from 3/4 Hp (0.56 kW) to 10 Hp (7.46 kW); silicon carbide seals and sediment traps; cast-iron impellers standard; approximate 36% wire-to-water efficiency.
• Energy and operating envelope — improved pump operating range and reduced energy consumption compared with previous designs; published average annual operating-cost savings are reported.

Options

• Compressed Air Purge Valve — evacuates fluid from the process circuit for faster, cleaner disconnection from molds and hoses.
• Modulating Cooling Valve — fully modulating cooling valve for consistent temperature control and elimination of water hammer.
• Alarm Packages — strobe light and alarm hardware to indicate alarm conditions.
• Stacking Rack — allows stacking of TCUs two-high; compatible with single-zone models only.
• Closed Circuit with Two Brazed Plate Heat Exchanger Sizes — higher performance, greater capacity, and reduced pressure drop.
• Communications Options — autostart/remote start, remote alarm dry contact, remote temperature sensor and other choices.
• Other selectable options — process line purge, choice of control points, auto restart, cool-down mode, remote start/stop, stainless-steel exterior panels, disconnect switch.
