TVT offers several convenient options to acquire our technology. Demonstration Lease Demonstration units are available for a minimum lease term of 4 months. TVT cannot guarantee the availability of demonstration units at any given time. Please contact us for availability. First and last payments are due upon execution of a purchase order and may be extended for up to 12 months. Lease rates vary based on the size of the application and the machine selected for maximum performance. Long Term Lease TVT can arrange for lease terms to satisfy most budgetary constraints through our financial institution's leasing agent. Terms and conditions vary based upon the size of the equipment, length of the lease and financial strength of the lessee. Please check with your finance department to insure that rates quoted are competitive. Purchase Option Terms and conditions of purchase require a 6-week lead-time. A non-refundable payment of 30% of the price of the equipment is required with purchase order; 30% due 30 days thereafter; 30% due upon delivery and the remaining 10% is due 30 days after delivery. Training Fee Customers may request a training certification for the lagoon operator. Our experience indicates that a knowledgeable operator will insure that the TVT solution will operate at peak performance. This one time fee of $800 (plus out-of-pocket expenses) provides one day of on-site instruction after installation. Maintenance Fee TVT offers an annual maintenance service, which includes monthly monitoring of performance and storage of site specific bacteria. Please contact us for a quote and specifics about this service.
