Banking on our 20 years of experience, we can rightfully say that our vibration analysis procedures are the best in the market. Instead of offering basic “analyze and fix” services, we’re taking a few steps ahead. We understand that all machinery are destined to malfunction at one point or another, so we often adopt advanced condition monitoring strategies. We’re also aware of technology’s importance for every processing plant. As part of our consultancy framework, we also emphasize the need for advanced technology.
Many of our clients in the past were already at their wit’s end when they approached us. Their machinery and infrastructure problems have already run deep, causing exponential troubles. Here at Stan Engineering & Analysis, we take each client’s problem in a unique scaffold. Even though vibration condition analysis is our flagship service, we didn’t stop there. We usually include logical methods and predictive planning to solve all our clients’ troubles. Some of our best clients are heavy industrial firms, chemical processing plants, refineries, and steel processors. We also offer in-depth vibration analysis for modeling companies.
As part of our growing services, we’re also offering phone consultations for all of our clients. In every phone consultation, we’ll take all angles of the problem objectively. This will help us come up of a possible solution to the client’s problems.
Our service scope is currently North America, but we;re receiving inquiries from many locations outside the US. In light of this, we’ll probably consider expanding our service scope to take in more clients.
