Thermo Savant RVT400-230 Retrofit-Ready Refrigerated Vapor Trap for RVT400 Series Control Systems
The Thermo Savant RVT400-230 (also referenced under part numbers 0020-20292 and E17317990) is a refrigerated vapor trap engineered for seamless integration into RVT400 Series vacuum systems. Designed as a retrofit-ready, drop-in replacement, this unit addresses the growing demand for reliable spare parts and upgrade components in laboratory and industrial vacuum environments where legacy equipment must remain operational without costly full-system overhauls.
Whether you are replacing a failed unit on an aging SpeedVac concentrator line, upgrading a vacuum manifold in a pharmaceutical processing suite, or restoring a freeze-dry system after an unplanned shutdown, the RVT400-230 delivers verified compatibility with the original RVT400 platform. Its 230V electrical configuration makes it directly applicable to European and international laboratory installations, eliminating the need for voltage conversion hardware during retrofit projects.
Procurement engineers and lab managers sourcing this unit should confirm the following before installation: input voltage and frequency compatibility (230V / 50–60Hz), refrigerant circuit integrity of the host system, trap inlet and outlet port dimensions against the existing vacuum manifold, and the condition of the cold finger assembly. In multi-stage vacuum setups where the RVT400-230 interfaces with a Thermo Savant SC210A SpeedVac concentrator or a Savant DNA120 SpeedVac, verifying the vacuum hose barb sizing and O-ring seat condition is critical to achieving rated trap performance post-installation.
For systems that also incorporate a Thermo Savant VP100 vacuum pump or a Savant OFP400 oil-free pump, the vapor trap serves as the primary solvent capture barrier protecting pump internals from corrosive or hazardous vapors. Replacing a degraded RVT400-230 before pump maintenance intervals can significantly extend pump service life and reduce total system downtime. In installations where a Savant UVS400 universal vacuum system controller is present, no firmware or parameter changes are required — the RVT400-230 is a passive thermal component with no digital interface dependencies.
Facilities running parallel vacuum lines with Thermo Savant RVT4104 or RVT100 series traps on adjacent benches should note that while the cold finger geometry is similar, the RVT400-230 is rated specifically for the RVT400 platform and should not be cross-installed without dimensional verification. For labs managing a mixed fleet of concentrators and vacuum systems, maintaining a stocked RVT400-230 as a critical spare reduces mean time to repair (MTTR) and supports continuous sample processing workflows.
All units supplied by SMARTNEXMSK are sourced from verified supply channels, functionally tested prior to dispatch, and covered by a 12-month warranty against manufacturing defects. Expedited shipping is available for urgent retrofit and breakdown recovery scenarios.

Retrofit Planning for Existing Vacuum Systems
A successful RVT400-230 retrofit begins with a systematic audit of the existing vacuum train. Start by isolating the vacuum circuit and allowing the existing trap to warm to ambient temperature before disconnection. Inspect the vacuum manifold tubing and all hose barb connections for cracks, hardening, or solvent contamination — these are common failure points in systems that have operated for more than three years without a full service cycle.
If the host system includes a Thermo Savant VP100 vacuum pump, drain and replace the pump oil at the same time as the trap swap to prevent cross-contamination of the new trap’s cold finger with residual solvent vapors from the pump. For systems using an OFP400 oil-free diaphragm pump, inspect the diaphragm and valve seats for solvent degradation before returning the system to service.
In multi-position concentrator setups where a Savant SC210A SpeedVac or DNA120 SpeedVac feeds into the RVT400-230, verify that the rotor and rotor seal on the concentrator are intact — a leaking rotor seal will overload the replacement trap and shorten its service life. Similarly, if a Savant UVS400 universal vacuum system controller is managing the vacuum schedule, confirm that the trap pre-cool cycle is programmed correctly to allow the RVT400-230 to reach operating temperature before the vacuum pump engages.
For facilities managing a broader fleet that includes RVT4104 cold traps or Savant RT490A refrigerated traps on adjacent lines, document the installation date and serial number of each RVT400-230 unit to support proactive replacement scheduling. Maintaining a minimum of one spare RVT400-230 in inventory is strongly recommended for labs with continuous or overnight run schedules where unplanned downtime carries significant sample loss risk.
Downtime Control During System Migration
Minimizing downtime during a vapor trap replacement requires preparation before the old unit is removed. Pre-stage the replacement RVT400-230 and allow it to reach thermal equilibrium in the lab environment (minimum 2 hours from cold storage) before installation. This prevents condensation on electrical connectors and ensures the compressor starts correctly on first power-up.
To protect ongoing sample runs, schedule the swap during a natural break in the processing cycle — ideally between centrifuge runs or at the end of a drying batch. If the system must be taken offline mid-run, cap all open sample tubes immediately upon venting the vacuum to prevent re-hydration of partially dried samples.
The RVT400-230 requires no software reconfiguration, address assignment, or HMI screen updates — it is a direct mechanical and electrical replacement. Once installed and powered, allow a minimum 15-minute pre-cool period before re-engaging the vacuum pump to confirm the trap is operating within its rated temperature range. Document the swap in the system maintenance log and retain the original part numbers (0020-20292 / E17317990) for warranty and traceability records.
For facilities with ISO or GMP documentation requirements, the 12-month warranty certificate supplied with each unit can be used as supporting evidence in equipment qualification (IQ/OQ) records, reducing the administrative burden of re-qualification after a like-for-like replacement.
Retrofit Support FAQ
Q: Is the RVT400-230 a direct replacement for the discontinued OEM part 0020-20292?
A: Yes. The RVT400-230 supplied under part numbers 0020-20292 and E17317990 is a verified drop-in replacement for the original Thermo Savant unit. No mechanical modifications are required for standard RVT400 Series installations.
Q: What pre-installation checks are required before fitting the replacement trap?
A: Confirm input voltage (230V), inspect vacuum port O-rings and hose barb connections, verify the host vacuum pump is serviceable, and ensure the cold finger cavity in the host system is clean and free of solvent residue before installing the new unit.
Q: How is the unit tested before shipment?
A: Each RVT400-230 undergoes a functional cooling performance test prior to dispatch. Units that do not reach rated cold finger temperature within the specified time are rejected. A test record is available upon request for GMP and ISO documentation purposes.
Q: What does the 12-month warranty cover?
A: The warranty covers manufacturing defects including compressor failure, refrigerant circuit faults, and electrical component failures under normal operating conditions. It does not cover damage resulting from incorrect voltage connection, physical impact, or contamination from improper installation. Warranty claims are processed within 5 business days of receipt of the returned unit.
