Support beyond the equipment

Buying a generator is the easy part. Getting a repeatable, documented cycle that passes qualification is where most projects need help. These services come with Fenggu VHP equipment.

01Free

Application review

Send us the space or equipment, materials, volume and what you need to achieve. An engineer recommends a configuration, explains the trade-offs and outlines what validation will involve — before any quotation.

02Project

Integration with existing equipment

Connect VHP to what you already have: closed-loop generators for biosafety cabinets, lyophilizers and centrifuges; HVAC-integrated systems that couple to existing air handling units without major rework.

03With equipment

Commissioning & cycle development

On-site installation and commissioning, then development of the cycle parameters — dehumidification, conditioning, concentration, dwell and aeration — for your space and load.

04With equipment

Validation support

DQ, IQ, OQ and PQ documentation support for the supplied equipment, biological-indicator testing of the developed cycle, and residual verification.

05With equipment

Training & maintenance

Operator training on running and recording cycles, and maintenance support to keep the system in its qualified state.

How a project runs

From first question to qualified cycle

  1. Application reviewYour volume, materials, process and targets.
  2. Configuration & quotationEquipment selection, utilities and scope of support.
  3. Manufacture & FATEquipment built and tested before shipment.
  4. Installation & commissioningOn site, connected to your space or equipment.
  5. Cycle development & validationParameters fixed, BI-tested and documented.
  6. Training & hand-overYour team runs and records cycles independently.
A note on scope. Fenggu is a VHP equipment manufacturer. Our cycle development and validation work supports the equipment we supply. If you only need a one-off decontamination with no equipment purchase, a dedicated decontamination service provider is usually the better route.
