Training and Support

To ensure optimum performance from your system, PVS offers customized training. PVS can train your engineers, maintenance personnel, and operators in everything from the basics of overall system operation and equipment sanitation to preventive maintenance servicing. 

Customer Service
The PVS Customer Service and Components Team are available to answer questions, assist with components and parts, and any other need that may arise.  They are reliable, friendly and technically trained to help you with any challenges or orders.

System Audits
The experienced staff of PVS are trained to perform extensive system audits to improve the overall performance to your automated ingredient handling system.  This includes:
• System Wellness
• Overall Performance
• Evaluation of Process Upgrades and Capital Improvements
• Maintenance and Housekeeping


Our research and development team creates innovative products to support our customers in an evolving marketplace. We develop and refine existing and new product concepts to uphold our standard to deliver high-quality solutions to customers. We collect and log real-time data about our customers’ production processes and use the information to inform our engineering direction and design. In the test facility, we also test new materials and ingredients to determine whether they can be conveyed and with what particular design, as well as what combination of components is necessary. 

The PVS test facility includes:
• Vacuum and pressure dilute transfer systems
• Vacuum dense phase, batch dense phase and low pressure         continuous dense phase systems
• Convey distances and elbows in multiple configurations to             simulate production environments
• Moisture, sieve and product degradation analysis (Soon!)
• Bulk density testing
• Discharge ability
    o  Slide angle testing
    o  Angle of repose
    o  Fluidization testing
• Test documentation

Toner Dust Collection System with Explosion Supression Package


Mechanical & Electrical - From silo setting through complete electrical wiring, PVS is dedicated to providing professional union and non-union installations. 

Site Supervision and Subcontract Management – PVS’s site supervisors provide a single point of responsibility for on-site installation activity. 


Installation Handoff – PVS employs an installation checklist that is used to confirm the completeness and accuracy of the installation and includes testing motor rotation, blower oil levels, and filter media installation. 

I/O Checkout 
I/O is checked for continuity through the control program to ensure proper address/physical point relationships. 

Field Engineering/Support
PVS’s controls team is an active part of the system commissioning effort. This allows us to make on-site modifications to operator interfaces or logic, freeing service technicians to focus on system performance and training. 

System “Site Acceptance” or “Dry Run” Testing
PVS suggests that a “dry run” of the system be completed to confirm the basic sequencing of the system components. This process minimizes ingredient waste and provides a time for program modifications to be made. 

Pre-Production Testing
With both a service technician and controls engineer on site, PVS can support a customer’s pre-production testing to confirm the convey rate and sequential performance of the system.

Project Management

PVS project managers work with the customer through every step of the project process. We consider our relationship with customers to be a true partnership, and our project managers are the point of constant contact throughout the entire process of a project. 

• Design process management

• Component logistic management

• Installation planning and coordination

• Commission planning and coordination

• Project control

• Customer satisfaction


PVS has a technical staff of process, mechanical, and electrical controls engineers who utilize the most advanced software and hardware solutions to engineer the right system for our customers. Our engineers design your system by combining PVS standard components with custom-designed equipment and incorporating additional process equipment into PVS’s scope of supply.

Dilute Phase Vacuum Conveying System

103-0302 Series Material Filter Receiver
The PVS Process Equipment 103-0302 Series Material Filter Receiver is designed to handle fine bulk materials in a vacuum type pneumatic conveying system. The modular design of the receiver allows flexibility in selection of construction material, power, filtration, receiver inlet size and type of discharge to meet your current and future application requirements.

Explosion Mitigation

PVS is familiar with the difficulties faced by manufacturers today of understanding how to comply with NFPA standards and the OSHA National Emphasis Program. At PVS, we assist you in comprehending what these standards mean to you and how they potentially impact your operation. Our goal is to help you make sense of the requirements and implement the most practical solutions for your needs. 

Below are documents that pertain to combustible dust compliance in the workplace. Manufacturers should have familiarity with these documents. Please feel free to contact PVS to discuss these standards and how they can affect your operation.

OSHA National Emphasis Program (NEP)

NFPA 654
Standard for the prevention of fire and dust explosions from the manufacturing, processing and handling of combustible articulate solids. Guide for determining which processes and vessels require protection

Standard for the prevention of fire in agricultural and food processing facilities. Guide for determining which processes and vessels require protection in the Food Industry.

Standard on Explosion protection by deflagration venting guide for venting of deflagrations. If you elect to use venting as a means of explosion protection, this document contains the necessary calculations for calculating the vent area required.

Standard on explosion prevention systems. Guide for determining the proper design for isolations and explosion prevention.
